Just to add to this topic...
I switched from 7.4 to 8.0 with cPanel and the community would NOT load on my server (blank page).
I switched back to 7.4 and everything loaded normally.
Called my hosting provider and chatted with them about the MySQLi extension and they told me a newer version of this was already installed on my server.
While we were talking, he switched it off and back on.
I switched back to 8.0 again and the community loaded normally.
*shrug*
Hope this helps somebody!
P.S. Apparently ioncube will not work with PHP8 and above (according to my hosting company)
