Hey, I think I just discovered another issue, which could relate to this one. I have modified the requesturl.php to accept the “fault” and I could continue. But on the next site it came up with another error message: is_dir(): open_basedir restriction in effect. File(/var/lib/php/sessions) is not within the allowed path(s): (/var/www/vhosts/hosting151828.a2eb8.netcup.net/:/tmp/)
And I fiddled a little bit with my browser and I found this error in the console area of my browser:
http://www.crazykoodaa.de/index.php/install/web_precondition/request_urls/20?_=1646489072967
If this is the main issue, then maybe there is a way to change the path?
