Sers! Me again. :/ The issue today is: My PMA is blank. Last thing I knowingly did was install php8.0 as additional version (See thread here: https://www.howtoforge.com/community/threads/ubuntu-18-additional-php8-0-startup-error.88012/ ). The database worked afterwards and still seems to do so - not sure if PMA worked then, as I was doing stuff on my development-VM (with ISPC and PMA) last night. System is Ubuntu18.04 with apache2 and mariaDB. ISPC works. Database connections work. Websites work. PMA is blank.
