Weird error PS 1.7.2.2 Call to undefined method Module::isEnabled()

[Vlad Popoiu]

Hello,

I encountered a weird error with my prestashop website. The website was running smoothly until the hosting provider decided they need to upgrade the server. They did it without any notice, and then the hell unleashed.

Website details:

Quote

 

PS Version: 1.7.7.2

Server software version: LiteSpeed

PHP Version: 7.3.33

Memory limit: 2048M

Max execution time: 300

Max upload size: 512M

MySQL version: 10.3.35-MariaDB

MySQL Engine: InnoDB

Driver MySQL: DbPDO

 

The problem:

The problem appears when trying to clear the cache, uninstall modules, or reset them.

After trying to do any of the tasks above, I get this error:

Attempted to call an undefined method named "isEnabled" of class "Module". [Symfony\Component\Debug\Exception\UndefinedMethodException 0]

As seen in the screenshots below, when trying to activate debug mode I get HTTP ERROR 500. This is when the website becomes unreachable by any means, front office and back office.

I tried activating debug mode before trying to uninstall any module, also, deactivated cache, overrides and forced compiling and I get this error:

After deleting cache from server, when accessing administration URL we get this error code:

Whoops, looks like something went wrong.

(1/1) UndefinedMethodException

The issue is not from caching, I deleted all cache from var folder, the problem still persists. The only way I can make the website live again is by recovering the files from yesterday or any day before, but the error is still there only it's not triggered yet.

What is your opinion on this error? I have never encountered it, and I do not seem to find a solution online for it.

My guess is it's something wrong with the server, because before the upgrade there was nothing wrong with the website. Same PHP version, no changes to the files, but he error appeared from nothing.

Thanks!

You are running an outdated version from PrestaShop together with a non-compatible PHP version:

https://devdocs.prestashop.com/1.7/basics/installation/system-requirements/#php-compatibility-chart

My advice would be to update PS to the latest version.

And the error is thrown by an override from the cookies module. I think you can rename /override/classes/Hook.php meanwhile.
