Re: Tiki 20.1 on RHEL8/CentOS8 (PHP 7.2)
"When completing the initialization and you get to start page, nothing appears. Just an empty HTTP 500 page."
At the end of the installation procedure, there is an optional attempt to add an alias from .htaccess to _htaccess to facilitate Clean URL. Maybe this is causing an issue?
If this is the case, try deleting the alias.
