1.7.6.5 Prestashop not taking into account php module modifications

[DEV MAJ]

Hi everybody,

I've been modifying a module and for some reason prestashop does not take into consideration the code modifications in module.php.

I've made modifications a while back and I need to modify it again due to an update that raises an error, the problem is that I get the error even if I remove said line.

I get this type of error: 

PHP message: PHP Notice: Undefined index: ordersorderFilter!active in /modules/module/module.php on line 104

 I've commented first than removed that line but I still get the error. It seems like there is a cache somewhere that I can't find, I've deactivated all possible cache in prestashop, activated debug mode, deleted the dev and prod folders in /var/cache/ but I still get the error. I've used grep on the server to try to find that line, and when I delete it from the file I can not find it anywhere else on the server (but can find it if I add it).

Anybody has any idea?

Thanks a lot!

The problem came from the hosting, the server had opcache activated and configured, we asked our admin to deactivate it, once it was deactivated, it worked fine
