Fix Joomla 6 Install Issue

I’m stuck at the database selection step while installing Joomla 6 on my cPanel server. The installer never shows a database driver even though both mysqli and mysqlnd are enabled.

Current stack
– PHP ea-php83 (8.3) with mysqlnd 8.4.16
– MySQL 8.0.45
– phpMyAdmin confirms mysqli, curl and mbstring extensions are loaded.

What I need
• Diagnose and correct the server-side misconfiguration that hides the database driver choice.
• Finish a clean Joomla 6 install using the default installation settings.
• Modify htaccess file modified to use https for site.
• Add site to Cloudflare and configure correctly for email.
• Provide a short report of the changes made so I can replicate them elsewhere.

I’m not sure whether other apps on this account could interfere, so please double-check that nothing else breaks in the process. SSH, cPanel/WHM and phpMyAdmin credentials will be provided as soon as we start.
