Hi, I suspect you have two different versions of the PS1.6 version 1 click upgrade module and will need updating via the modules page or manually. Don't install/use the PS1.7 version 1 click upgrade module (3.0.4) via addons store it is not compatible with PS1.6 and will crash your website. Option showing 1.6.1.17 to PS1.7.2.0 is a beta version (1.6.7) 1 click upgrade (Don't use this it is faulty and will cause problems with further upgrades etc once in PS1.7 environment) Option showing 1.6.1.17 to 1.6.1.18 is showing correct option available using a current release module or older then above beta module of 1 click upgrade. Sadly it is not possible to successfully upgrade from PS1.6 to PS1.7 via 1 click upgrade at the moment. If keen to test PS1.7 with your data it is possible via third party modules or database export and import.... requires a lot of effort and understanding of database (not a simple export/import). Some very good articles and tools on here if interested in trying. Suggest waiting til end of life PS1.6 (only a few more months) then hopefully upgrade via a newly released 1 click upgrade module (fingers crossed) and if all else fails and your keen to stay with Prestashop do a clean install of latest version, start again from scratch and manually import old data/images.

Well done for stop wasting your time and I'm sure frustration at Prestashop trying to upgrade via the 1 click upgrade. I ended up comparing and learning the database differences and changes from 1.6 to 1.7 so I can do it manually. Some great work done by another member rynraf worth a read https://www.prestashop.com/forums/topic/636877-almost-complete-tutorial-how-to-migrate-data-products-customers-orders-from-prestashop-16-to-prestashop-17-version/ I can now modify, export and import the relevant database and PS files and create a test PS1.7.2.4 version. Still waiting for 1.7.3 stable before playing again (1.7.3 is still beta) Quote from build.prestashop.com today as I was checking if 1.7.3 rc released PrestaShop Loves You! <3 Hope that makes us all feel better as I'm not sure anymore if the community loves Prestashop back

Thanks for your feedback. Recommend Export/Import relevant database data to a clean install to test PS1.7.x.x PS1.7.3.x should be out soon to play with. PS1.7.1.0 to 1.7.2.3 have security issues best to avoid all together. PS1.6 - it works even if it's not “state of the art” right now.

Solution found. Still waiting on a reply/input from prestashop..... 1 Click upgrade is faulty for me. If I successfully upgrade using the beta 1 click upgrade (1.6.7) from 1.6.x.x to 1.7.2.0 it will fail further upgrades for later versions (1.7.2.x etc) with ajax server error (database issue). If trying to upgrade using PS1.6.1.17 (1.6.8) 1 click upgrade - Fails with ajax server error (database issue). If trying to upgrade using PS1.7.2.0 (3.0.3) 1 click upgrade - Fails with ajax server error (database issue). Work around - Solution How did I upgrade and evaluate PS 1.7.2.4 with my data. Export customers, orders, categories and products using Store Manager (great tool not made by prestashop they have a 30 day trial, I use the paid version) Clean install 1.7.2.4 and import store data (I tried clean 1.7.2.3 and imported data then tested upgrading to 1.7.2.4 and worked fine no AJAX server error) Start setting up shop again (slow but clean start with no old modules/themes etc) At the end of the day the import/export option is the better way for me to test/upgrade PS1.7.x.x (time consuming yes but clean start) I'm not using PS1.7 in any Production environments at the moment as PS1.6.1.x works well for me. I will keep testing PS1.7.x.x versions, wait for PS1.8 and try other e-commerce platforms for new projects. What I want to say to Prestashop but should I? Yes Prestashop you should get involved in your forum for the community that use Prestashop and reply to questions posted it's not professional not being involved. So many forum questions go unanswered imagine the sales growth (once you fix the addon store) you would get from contributing and showing you really care for the users.

Solution found.

Hi looking into this error as well on a different post feel free to add to my post any feedback suspect it's related, thanks Below is just one of the ways I can reproduce error with the the PHP error log. I will try and relook at when I get a bit of free time - Hope it helps I think it will be an easy tweak to fix. #2 Working from 1.6.1.17 to 1.7.2.0 only then failed at further upgrade to 1.7.2.3 - Downgrade 1clickmodule to (1.6.7) in 1.6.1.17 from build.prestashop.com from article about a year old - choose major and follow prompts - It upgraded to 1.7.2.0 Tried to upgrade 1.7.2.0 via latest updated 1clickupgrade module (3.0.3) and it failed at database upgrade (same error as before) - [Ajax / Server Error for action upgradeDb] textStatus: "error " errorThrown:"Internal Server Error " jqXHR: " " PHP error [22-Oct-2017 17:04:59 Europe/Paris] PHP Notice: Use of undefined constant _PS_INSTALL_LANGS_PATH_ - assumed '_PS_INSTALL_LANGS_PATH_' in C:\xampp\htdocs\prestashop\src\PrestaShopBundle\Install\LanguageList.php on line 68 [22-Oct-2017 17:04:59 Europe/Paris] PHP Fatal error: Uncaught Error: Class 'PrestashopInstallerException' not found in C:\xampp\htdocs\prestashop\src\PrestaShopBundle\Install\LanguageList.php:69 Stack trace: #0 C:\xampp\htdocs\prestashop\src\PrestaShopBundle\Install\LanguageList.php(60): PrestaShopBundle\Install\LanguageList->__construct() #1 C:\xampp\htdocs\prestashop\admin1234\autoupgrade\latest\install\upgrade\php\migrate_tabs_17.php(56): PrestaShopBundle\Install\LanguageList::getInstance() #2 C:\xampp\htdocs\prestashop\modules\autoupgrade\AdminSelfUpgrade.php(2312): migrate_tabs_17() #3 C:\xampp\htdocs\prestashop\modules\autoupgrade\AdminSelfUpgrade.php(1992): AdminSelfUpgrade->doUpgrade() #4 C:\xampp\htdocs\prestashop\admin1234\autoupgrade\ajax-upgradetab.php(90): AdminSelfUpgrade->ajaxProcessUpgradeDb() #5 {main} thrown in C:\xampp\htdocs\prestashop\src\PrestaShopBundle\Install\LanguageList.php on line 69

Getting closer some info so far - both errors the same just need to sort out the language part and might have success with both upgrade options Some things I tried #1 Not Working for me - Standard 1clickupgrade module (1.6.8) in 1.6.1.17 and choose advanced option - local archive - used and stored in admin/autoupgrade/download a modified 1.7.2.3 zip file as the 1clickupgrade modules needs it in the old 1.6 download format - Folder [prestashop/1.7 files] - zipped or it will not be found (1.7 download zip different) End result once upgrade started - [Ajax / Server Error for action upgradeDb] textStatus: "error " errorThrown:"Internal Server Error " jqXHR: " " #2 Working from 1.6.1.17 to 1.7.2.0 only then failed at further upgrade to 1.7.2.3 - Downgrade 1clickmodule to (1.6.7) in 1.6.1.17 from build.prestashop.com from article about a year old - choose major and follow prompts - It upgraded to 1.7.2.0 Tried to upgrade 1.7.2.0 via latest updated 1clickupgrade module (3.0.3) and it failed at database upgrade (same error as before) - [Ajax / Server Error for action upgradeDb] textStatus: "error " errorThrown:"Internal Server Error " jqXHR: " " PHP error [22-Oct-2017 17:04:59 Europe/Paris] PHP Notice: Use of undefined constant _PS_INSTALL_LANGS_PATH_ - assumed '_PS_INSTALL_LANGS_PATH_' in C:\xampp\htdocs\prestashop\src\PrestaShopBundle\Install\LanguageList.php on line 68 [22-Oct-2017 17:04:59 Europe/Paris] PHP Fatal error: Uncaught Error: Class 'PrestashopInstallerException' not found in C:\xampp\htdocs\prestashop\src\PrestaShopBundle\Install\LanguageList.php:69 Stack trace: #0 C:\xampp\htdocs\prestashop\src\PrestaShopBundle\Install\LanguageList.php(60): PrestaShopBundle\Install\LanguageList->__construct() #1 C:\xampp\htdocs\prestashop\admin1234\autoupgrade\latest\install\upgrade\php\migrate_tabs_17.php(56): PrestaShopBundle\Install\LanguageList::getInstance() #2 C:\xampp\htdocs\prestashop\modules\autoupgrade\AdminSelfUpgrade.php(2312): migrate_tabs_17() #3 C:\xampp\htdocs\prestashop\modules\autoupgrade\AdminSelfUpgrade.php(1992): AdminSelfUpgrade->doUpgrade() #4 C:\xampp\htdocs\prestashop\admin1234\autoupgrade\ajax-upgradetab.php(90): AdminSelfUpgrade->ajaxProcessUpgradeDb() #5 {main} thrown in C:\xampp\htdocs\prestashop\src\PrestaShopBundle\Install\LanguageList.php on line 69

Getting sick of seeing this error Prestashop must be able to reproduce this error internally. http://forge.prestashop.com/browse/BOOM-3946 All files upgraded. Now upgrading database... [Ajax / Server Error for action upgradeDb] textStatus: "error " errorThrown:"Internal Server Error " jqXHR: " "

Hi El Patron and thanks for your reply and contributions to prestashop. I'm sure most of us could hack, export and import the required info to get it working. But how many of the 100's of client shop upgrades worked successfully with the 1 click upgrade module ? My question is more to benefit the community trying to upgrade not just me. 1.7.x.x has been out a long time now does the 1 click upgrade option work for anyone from 1.6.x.x to 1.7.x.x? If not on clean install of 1.6.x.x why not? I think most people having to start again just to have the latest prestashop version, spend $$$ on new modules / themes / time will look at other e-commerce platforms which is sad for us all. Easy way to test if anyone has time Clean install 1.6.x.x (so no old modules or themes interfere) suggest the latest version and upgrade it via the 1 click upgrade module to latest 1.7.x.x- did it work? If anyone gets it to work or tweaks reply with steps taken. I will be trying a few things over the next few days. Thanks

Clean install PS 1.6.1.17 no changes and trying to upgrade to PS 1.7.2.3 = FAIL Should this work and has anyone been successful in upgrading via 1 click upgrade from 1.6.x.x to 1.7.x.x Please share results so people trying have some guide to follow or just not try because it doesn't work. Prestashop feel free to contribute and don't be a faceless stranger to the forum. A year into 1.6 Maintenance - The way forward - Not quiet there yet. build.prestashop.com

Thanks eleazar, appreciated. Only seen this utilised with latest paypal module in my situation. Doesn't even show anything on invoice when payment is from bank wire. You suggested load old module with bugs, I suggested remove code on invoice to hide one of the bugs. None are great options. What's more important is why is the module faulty and not fixed as an official prestashop module on addons site...........

Like?

Hi, Had same issue with this showing on invoice as a work around I excluded that part from within pdf/invoice.tpl It's located at the bottom of the invoice.tpl file Add <!-- between code below --> or just delete that code and save. Test - view invoice back office for relevant order. Note: when you upgrade prestashop this mod will be changed back. If using latest paypal module you may want to check below. The paypal/cards logo at the checkout (payment options) may not be displayed (No image) incorrect image path (region specific issue).

That's seems like a module enabled have a look in modules and disable it or configure it maybe = hardevelmulticurrency (test for dramas) Suggest put shop in maintenance when playing. Backup suspected module Currency.php if you havn't already then create the Currency.php I mentioned before in the override/classes Clear cache and try manual sync of currencies. Feels like your getting closer (999 things to do only 998 soon). Can still see your external link in the first post

What is this small 22-line Currency.php file in your /override/classes/ directory Default PS1.6.1.7 is no Currency.php file in override/classes suggests other changes somewhere Suggest removing link in your first post as it shows your admin location etc.
