1. What's new in 1.4.5.1?
A. A lot - check here
2. Will upgrading screw up my modules, themes, etc?
A. If you are running 1.4.x, then your modules, themes, etc should be fine as 1.4.5.1 is based off the same codebase. However, if you have modified any core files, these modifications are likely to be overwritten in the upgrade process.
Upgrade process
3. I am running version 1.3.x or 1.4.x at the moment. How do I upgrade?
A. Upgrading is simple; read instructions here or watch video here
But wait! You don't have to! PrestaShop has now released (thanks Michaël Marinetti) an autoupgrade module which will do all the work for you. You can download the module and check out the instructions here. While it has been released as a module to help legacy installations, from now on, autoupgrade will be a part of the core software.
Upgrading with Autoupgrade module
4. I am unable to install Autoupgrade module. What can I do?
A. First, try changing default language to English. Then uninstall and install the module again.
5. I have installed the module and started step 4 of Mike Kranzler's instructions. Selected “No” under "Shop Desactivated", but can't see “Enable Shop”!!
A. "Shop Desactivated" and “Enable Shop” are actually on 2 different pages. Selecting “No” under "Shop Desactivated" is designed to redirect you to the page where you find “Enable Shop”. If for any reason (e.g. if "Shop Desactivated" was already "No" in your shop) the redirect doesn't work, then go to Preferences tab, and you'll find “Enable Shop” right at the top.
6. I have finished step 5 of Mike's instructions, but do not see the "Upgrade Prestashop Now!" button.
A. That happens sometimes. Click "Click here to refresh" button (you will find it somewhere below "Last version is 1.4.5.1 final (1.4.5.1)").
7. Clicked "Upgrade Prestashop Now!" button, but getting error.
[Server Error] Status message : error
A. If you are using shared hosting like godaddy or 1and1, it is highly likely that this is caused because of a server timeout. In your hosting account root, find the php5.ini file and add/edit max_execution_time line so that it looks like:
max_execution_time = 300To be sure, do the same in php.ini
You may need to wait up to 24 hours (depending on the time at which the host resets servers) for this to take effect.
If even 24 hours after making the above change, on hitting "Upgrade Prestashop Now!" you still get the same error, then in your PS files, change Line 29 in /config/config.inc.php from
@ini_set('display_errors', 'off');
to@ini_set('display_errors', 'on');
Then open your Prestashop backoffice in Firefox.Start Firebug (you'll need to have it already installed).
In Firebug, click Console Tab, then Errors subtab
Then in your PS backoffice, hit "Upgrade Prestashop Now!" again.
Take a screenshot of the errors (e.g. with Windows 7 Snipping Tool) and save the image
Send this screenshot to US Community Manager Mike Kranzler - he will be happy to help
8. I am getting an error during backup.
error during backupDB
A. If you have cache (memcache or filesystem cache) enabled (BackOffice > Preferences > Performace), please disable it and try again.
9. I am having problems with blocklayered module after completing upgrade!
A. Go to BackOffice > Preferences > Performace
Disable cache (at the bottom of the page)
Disable Force Compile (at top of the page)
10. I installed the Autoupdate module fine, but I don't see the Tools > Upgrade tab that I am supposed to go to.
You are probably using an old version of PS...there was a bug with displaying tabs. In the URL, next to your PS base, add /admin/index.php?tab=AdminSelfUpgrade (replace /admin/ with whatever you have renamed admin folder to). This should take you directly to the upgrade page.
If you are running 1.4.x then it's probably a permission issue. To fix this:
Go in Employee > Tabs and check if the tab "Upgrade" is created. If yes, then delete it. Then, create a new employee:
name : Upgrade
class : AdminSelfUpgrade
module : autoupgrade
parent: Tools
The tab should now appear when you go on tab Tools
11. The process stop when "backupFiles" immediately. How to fix that ?
Your php configuration does not have the "ZipArchive" extension, and the module need it for backup files. This will be fixed in a future release of that module.
12. The process stop when "unzip". How to fix that ?
This can be a write permission problem. Please check the user which runs apache has proper rights to all your admin/autoupgrade/ directory.
