Error: There has been a critical error on this website.Learn more about troubleshooting WordPress. There has been a critical error on this website.
What I tried to fix:
I manually installed PHP 8 because I think it’s PHP related (even if the 7.4 didn’t worked neither), running (as root):
apt install lsphp80
and restarted server.
But it didn’t fixed the issue.
I’ve been able to reproduce the same issue like 3-4 times after a clean install of Ubuntu.
Would you be kind enough to help me please?
