PHP Fatal error with PHP 8.3

[petitramen-png]

Hello,

I have been using Shaarli for quite some years, but I had recently to update my PHP version to 8.3 for my other websites. Since, I got a 500 error when I try to access Shaarli. On my log, here is what I have:

[02-Aug-2025 16:26:30 UTC] PHP Deprecated: Return type of LinkDB::offsetUnset($offset) should either be compatible with ArrayAccess::offsetUnset(mixed $offset): void, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /home/whdk4898/ramenos.net/liens/application/LinkDB.php on line 171

[02-Aug-2025 16:26:30 UTC] PHP Fatal error: Uncaught Error: Shaarli\Security\LoginManager::__construct(): Argument #1 ($globals) could not be passed by reference in /home/whdk4898/ramenos.net/liens/index.php:126
Stack trace:
#0 {main}
thrown in /home/whdk4898/ramenos.net/liens/index.php on line 126

Could you please let me know what I should do? Do I need to enable a specific PHP extension on cPanel? Something else?

Thanks a lot for your help.
