There may be a PHP.ini setting to defeat this, but as of PHP 9+, these will be fatal errors.



 

Noted. However, v11 does not support PHP 9 as PHP 9 has not yet been released. I don't think it will (or if it does, it'll probably be a later minor version like 11.1).

You can disable those errors under Setup → Configuration → Site options → Error handling

I solved this very easy.

In .htaccess file (root file) you need to add following lines:

<FilesMatch "\.(inc|php5|php4|php3|php2|php|phtml)$">
SetHandler application/x-lsphp74
</FilesMatch>

I have several webpages, and now I am strugling with Joomla…. And latest version runs only on php 8.x, so I have tons of "Deprecated…." messages, very anoying for working in admin panel.

Since change in .htaccess works like a charm. Composr and Joomla.

Awesome to hear. I do know Composr is not compatible with PHP 8.2 yet. It's only good up to 8.0 and partially 8.1 I believe.
