I downloaded the version marked as compatible with MediaWiki 1.42.1 - PluggableAuth-REL1_42-b35addc.
However, I am receiving the message "Could not load authentication plugin". I am using SAML, so I also updated SimpleSAMLphp to the 1.42.1 version of that extension.
I had updated my PHP to 8.3.# since it is now compatible with this new version of MediaWiki. The error I got with that version of PHP indicated that there was deprecated code in PluggableAuth.
Deprecated: "Creation of dynamic property MediaWiki\Extension\PluggableAuth\BeginAuthenticationRequest::$pluggableauthlogin0 is deprecated in /var/www/html/includes/session/Session.php"
When I downgraded back to PHP 8.1#, the detailed error message disappeared, and I am now stuck with the vague message "Could not load authentication plugin".
Has anyone else experienced this. I am wondering if the current version of PluggableAuth is truly compatible with MediaWiki 1.42.1
