Cannot migrate to IONOS server with starter-kit

Hey there,

I just trying to move a Kirby Starterin to a new IONOS Webserver that unfortunately “blocks” my Kirby backend. I set php Version to 8.0.

If I want to access my panel I get an Internal Server Error:
The server encountered an internal error or misconfiguration and was unable to complete your request.

here’s the site

I’m a bit helpless what I should do next? I’ve never had any issues with STRATO webhostings.

Thanks in advance.


EDIT: Looks like I could solve it by adding

RewriteBase /

to my htaccess file.
