Prestashop 9.0.1 Homepage white

[Kingtonino]

Hi everyone, suddenly my homepage has turned completely white. I restored the domain and database from a backup, but the problem is still not resolved. What else can I do? Could it be an issue with my Aruba hosting? The site is casageniale.it

Hi,

A white homepage after upgrade usually means a PHP fatal error. Here's how to quickly identify the problem:

1. First, enable debug mode:

   Edit /config/defines.inc.php

   Change define('_PS_MODE_DEV_', false); to true

   Save and refresh your homepage

   This will show the actual error message instead of the white screen.

2. If you prefer to test modules:

   Via FTP, go to /modules folder

   Rename individual module folders (add .backup to folder names)

   Start with third-party modules, especially recently updated ones, and refresh homepage after each change.

3. Clear cache:

   Delete all files in /var/cache folder

The debug mode approach is fastest - it will immediately point to the exact file or module causing the issue.

Once you see the error message, we can provide the specific fix.

Regards.
