Apache2, mod-evasive and Joomla Installation Problems
While upgrading my server, most probably while doing the upgrade to Ubuntu 20.04 Focal, mod-evasive got installed and enabled. It didn't effect the configured websites, except sometimes for a couple of seconds I received 403 errors. But finally everything continued working. The problem started, after adding a new website and trying to install a new Joomla platform. The installation process of Joomla stopped on the very last step without any error message on the screen.
