SOLVED: (1/1) ContextErrorException Notice: Undefined variable: id_category after upgrade to 1.7.8.7

Mathew Nwaneri · August 17, 2022

Hello everyone,

Hopefully someone can assist me il resolving this bug.

With the recent attack on core prestashop, I unwillingly upgraded as to be safe, unfortunately this has caused a devastating situation on my site.

Front end is working as supposed.

I have resolved all errors I'm having except for backend login.

I get a 500 error when I open admin url, from debug I get the following notice:

Whoops, looks like something went wrong.
(1/1) ContextErrorException
Notice: Undefined variable: id_category
in ProductController.php line 1244
at ProductControllerCore->getBreadcrumbLinks()
in FrontController.php line 1736
at FrontControllerCore->getBreadcrumb()
in FrontController.php line 533
at FrontControllerCore->assignGeneralPurposeVariables()
in FrontController.php line 590
at FrontControllerCore->initContent()
in ProductController.php line 417
at ProductControllerCore->initContent()
in Controller.php line 306
at ControllerCore->run()
in Dispatcher.php line 518
at DispatcherCore->dispatch()
in index.php line 28

I've tried all I can, unfortunately without solution.

Below is the script for the ProductController.php to which I don't know how to solve the generated error.

Can somebody be kind enough to assist me? at least to be able to get into admin.

Thanks for your assistance.

Best regards

did you try this?

Good morning @stifler97,

Thanks for your kind reply, unfortunately it has nothing to do with my error i'm facing.

I cannot access back office in any way 😞, *500 Server Error Oops, something went wrong. Try to refresh this page or feel free to contact us if the problem persists.*

I've also checked database ps_category table and all is as supposed, it did tweak a bit without success, so i put it back as it was.

One strange thing I noticed is that when I delete the public_html/var folder, logs does not regenerate as supposed which causes and additional, then i have to manually create it to remove the error.

Also, checking the logs file in public_html/var/logs, i have loads of these:

*ERROR* 	v1.7.8.7	2022/08/18 - 08:30:38: Link to database cannot be established: SQLSTATE[HY000] [1203] User mydatabase_user already has more than &#039;max_user_connections&#039; active connections at line 136 in file classes/db/DbPDO.php

Front end is working perfectly without errors.

Kind regards.

Hi everybody,

I tried roll back to old database version, no luck.

I resolved by replacing my public_html directory to its last working version "1.7.8.5" and the error disappeared, luckily I had it.

I guess there's a bug in the "1.7.8.7" or it just doesn't fit with my hosting.

Database remains the upgraded version so no roll back was made.

I am on a2hosting dedicated Turbo + LiteSpeed Cache + LiteMage:

Thanks to all and be blessed.
