Back office wont save or work properly after upgrade

[escaper]

Hello,

 

After updating prestashop from 1.4.10 to 1.5.4.1 back office becomes all sketchy.

First it wont save any settings, lets say changing a theme or language clicking green save button does nothing(sometimes it goes to the top of the page).

Second, on modules/dropdowns that use some sort of jquery(like my theme config panel does) it all becomes unresponsive and there is no way of saving settings.

 

Debug gives me no information, there are no errors that occur. Only thing i get is in my browser console, following two errors:

Uncaught SyntaxError: Unexpected token ; index.php:17
Uncaught ReferenceError: youEditFieldFor is not defined notifications.js:4

 

It happens with auto upgrade and with manual one. It just wont save anything and it seems like javascript/ajax fail to work.

 

I appreciate if you can help, or give me some idea to work with. Thanks!

Hi escaper,

 

I would try these things first:

 

Clear cookies and cache for your domain. Alternatively you can access your adminpanel in an incognito window (firefox is CTRL + SHIFT + P, Chrome is CTRL + SHIFT + N)

 

Manually upload the /js/ and admin directory from the original Prestashop 1.5.4.1 zip file. Rename current js folder to "js OLD".

 

Do you have some modules that modify the adminpanel? Try temporarily removing those.

 

Try and rename your /override/ folder to "override OLD" and upload the original override folder from the Prestashop 1.5.4.1 zip file.

Thanks for your help, unfortunately none of those seem to work. I ran out of ideas, last thing that comes to mind is a database or something that breaks during upgrade.

 

Is there a way in 1.4 to just disable all modules?

Is there a way in 1.4 to just disable all modules?

 

I'd suggest you just open the modules overview and then proceed to click "Disable", all the way down, with your middle mouse button. Then you can quickly go through them all.

 

Remember when you upgrade you can (in the advanced section) configure it to disable all non-native modules for you.

 

 

If you have tried using 100% original js and admin directory files, and not using any override files, then it must be some module that is messing things up.
