When I have read the line "To install osTicket, your web server must have PHP 8.0 and MySQL 5.0 (or better) installed." I did understand that PHP 8.0 is the minimum required version. Its not saying "exactly" either. Thanks anyways for the clarification. In my Webhosting dashboard on Plesk, I can also select PHP 8.0.19. As you said PHP 8.0.x then 8.0.19 should work, correct?
I have tested with PHP 8.0.19 with same issue HTTP ERROR 500 .
Does anyone have a suggestion? Maybe downgrade?
Its tricky because I had version 7.x and all my tickets were suddenly empty with no content. No idea why, thats why Im trying to figure out what the issue could be. I "hope" its because I need PHP version 8
