Hi,  so today i loged in and i find out that im unable to edit products, it is looking messed up, so i opened console and i can see this:  

jquery.ui.core.min.js:4 Uncaught ReferenceError: jQuery is not defined
    at jquery.ui.core.min.js:4

So i checked source code, how can i edit order, to call jquery-1.11.0.min.js as first?  Or is problem somewhere else? (we did uninstall Merchant Expertise module but not sure if this is the cause)

We are runnin 1.6.1.10

Have you changed anything besides uninstalling Merchant Expertise? have you tryed to install it again? Can you check what version of PHP and SQL your server is using? (they might have changed the PHP version without noticing you)… Have you tryed disabling all extra modules? and enter debug mode?

Best Regards

There is too many admin accounts so i cant answer 1Q to 100% but to my knowlidge no, and yes i did try install and unsintall, alse no changes on server side,  its 5.6 and MariaDB 10.1.

I disabled all modules, overrides did not helped too, and debug mode turned on and no errors are showen.

Can you tray PHP version 7.1! -> https://devdocs.prestashop.com/1.7/basics/installation/system-requirements/

You can also check the permissions on your files, and don´t forget to clear/disable the cache!

Do you have a full backup of the store? you can recover it to a point where it was working!

Some jquery file or related file might have gotten corrupted. It looks like it´s not loading or some variables are missing!

Remember ALLWAYS BACKUP FIRST...

Right now im unable to do so, its old, big and messy - and orders are coming in waves - i ll have to w8 to 24th evening or so when traffic is low. And we are unable to run 7.1 ..So backup is only solution - its like nightmare coming alive, either way thank you for advice

well fixed - culprit here was geispoint module, so if anyone encounter same issue just disable overrrides and non presta native moduls, if that help just turn modules on a disable one by one
