Hi,
I have a similar error. After moving the shop (v1.7.6.0) from the sub directory /PS/ in my domain to the roo, changing the URI inside prestashop and clearing the cache, I can't access the modules->alert page or the modules->update page and get errors when I try and disable a module on the page.
The error log shows that all modules are still pointing towards the old subdirectory.
After reading this I tried to:
- remove the /var/cache/ folder (had to create an empty folder as nginx did not want to start anymore. -> no luck
- went into the DB and disabled a few modules (I use the eicaptcha module) -> returning to the module page, multiple refreshed, removing the cache directory as well as clearing the cache from within PS backend and still the disables modules show up as enabled
Bit at a loss here how to proceed next.
Thanks for the help in avance.
