Hello,
I changed the _PS_MODE_DEV_ value from "false" to "true" in defines.inc.php.
I noticed that my site was full of errors.
And that's when I realised why I couldn't update my site, which is currently in version 1.6.1.24.
Public part error

Can you tell me where the problem is, and how to fix it?
Thank you in advance
