The Forum Post Assistant (FPA) script has been developed to assist Joomla!® forum posters to be able to post relevant system, instance, PHP and troubleshooting information directly in to a pre-formatted forum post. This will save a few hours of posting back and forth, asking for, and explaining how to acquire useful information in order for other forum users to help troubleshoot a problem.
FPA v1.6.1 fails in PHP 8.0 with HTTP 500 error because two calls to the function mysqli_connect_errno() in line 2365 have arguments.
