I had a look at the code in and this is what is on line 534

Code:

532 function render_category_literal_description($desc)
533 {
534   return strip_tags($desc, '<span><p><a><br><b><i><small><big><strong><em>')
    ;
535 }

Deprecated means just deprecated, it's not an error, functionality will cease to exist in later PHP versions. You can suppress such messages like in [Forum, post 183126 by erAck in topic 31852] Menubar tags issue after 12.2.0 upgrade or rather log them like in [Forum, post 180778 by erAck in topic 31258] Error Message.

Apart from that, Piwigo is simply not ready for PHP 8.1, it barely works with PHP 8.0 but still has quirks with it, the only safe version to use is PHP 7.4.

OK Thanks for the help, I added the foolowing to my config file at /piwigo/include/config_default.inc.php

Code:

$conf['show_php_errors'] = E_ALL & ~E_NOTICE & ~E_DEPRECATED & ~E_WARNING;

The messages on the screen have stopped.

I had my own bitter lot with PHP. Once I updated it to the latest version and it crashed my site as the CMS did not support it. So later when I needed some apps for my business I handled it to [-link-removed-] to avoid any further complicaitons. Another advantage will be the cost effectiveness, but that you can check by yourself already.

I had no idea how to deal with this error myself, but I'm glad I found this page
