Hello/Hi/Greetings,
I was looking through the error log and came across the following two messages:
AH01071: Got error 'PHP message: PHP Deprecated: implode(): Passing glue string after array is deprecated. Swap the parameters in /path_to_site/public_html/include/dblayer/functions_mysqli.inc.php on line 688'
AH01071: Got error 'PHP message: PHP Notice: Undefined index: category in /path_to_site/public_html/plugins/prevnext/include/public_events.inc.php on line 62 PHP message: PHP Notice: Trying to access array offset on value of type null in /path_to_site/public_html/plugins/prevnext/include/public_events.inc.php on line 62'
Looks like one is main piwigo and the other a plugin.

The 'Deprecated' is just that, a deprecation message, meaning functionality may cease to exist in some future version of PHP. Search the forum for how to suppress the deprecated messages.
The PrevNext plugin may just be too old (unchanged since 2016) to properly work with PHP 7.4, you could try if using PHP 7.3 or 7.2 would solve that.
