Can not get Debug mode to work in Prestashop 1.6.1.5

[MarlboroMan]

Hi

 

Please help? I urgently need to get debug mode to work in Prestashop 1.6.1.5.

 

I did change the below files in config\defines.inc.php  

 

define('_PS_MODE_DEV_', true);

@ini_set('display_errors', 'on');

 

Do I need to change anything else?

Changing the value of _PS_MODE_DEV_ from false to true is all you need to do to enable debug mode. Error messages should begin appearing instead of blank pages after doing that.

on a separate note, PS v1.6.1.5 was a faulty version of Prestashop, quickly replaced by PS v1.6.1.6, I would suggest upgrading

Hi Guys

 

By changing the value of _PS_MODE_DEV_ from false to true I get no screen with errors. How can I see why my product changes will not save or save and stay?

Are there a way to upgrade my site without loosing the changes I have done?

Sounds like your AJAX calls are failing, in which case you'll need to find the red AJAX call in the Firebug console and then check the Response tab to see the error message. It's possible it is a file permissions issue or a programming issue.

 

If you've made all your changes to PrestaShop as overrides, then it's safe to upgrade without loses your changes. You'll lose all non-override changes in the upgrade and need to re-apply them, so keep a log of your changes and make a backup of your site before upgrading so you can refer back to it if needed.

When I first started with Prestashop I did not know about the overrides so I made the changes directly. I guess my options are to try and fix my current version or start over with a new version.

 

For now I will try to trouble shoot.

Please explain how to do the above mentioned?

You'll need to install Firefox with the Firebug extension if you haven't already and then press F12 to open Firebug. Then edit a product and you should see something like the following:

 

As you can see, there are no errors on my PrestaShop v1.6.1.7 test site. In your case, there will be some AJAX calls that are red instead of black. Click the + icon on the left to view the error message in the Response tab. If you have enabled _PS_MODE_DEV_, there should be an error message there that can be used to debug.

I've added some extra text to one of my product description and clicked on save and stay. The page then refreshes without saving the new added text but all the lines in firebug are black.

 

I've also tried adding to cart then receive a "Your shopping cart is empty." message but the firebug screen was blank.

Weird. Sounds like something is preventing data being written to the database. It's possible your MySQL user doesn't have permission to write to the database. I'm not sure what else would cause that level problem, except maybe an override that is causing it.

Why only in google? If I use another browser the save function works perfectly also the add to cart work.

I have no idea. Doesn't make any sense. Have you tried on another computer?

Hi Rocky

 

I've decided to build a new shop from scratch with Prestashop ver1.6.1.7 as upgrading will have to many complications.

Will I be able to copy all existing customers,orders,products,categories and images into the new site?

PrestaShop doesn't come with an option to transfer data from one database to another. You should be able to use the 1-Click Upgrade module to upgrade to PrestaShop v1.6.1.7 and preserve your data.
