cannot Save System Settings

Well HTTP Error 500 is a pretty generic error.

My advice would be to check your log file. That should give you more specifics to look into.

OK then, I checked the error logfile. This is what I get after trying to save the settings:

[Thu Oct 19 22:46:45 2006] [error] [client 84.41.158.47] mod_security: Access denied with code 500. Pattern match "\\\\.ph(p(3|4)?).*path=(http|https|ftp)\\\\:/" at REQUEST_URI [hostname "shop.mydomain.nl"] [uri "/zc_install/index.php?main_page=phpbb_setup&language=english&physical_path=/home/httpd/vhosts/mydomain/subdomains/shop/httpdocs&virtual_http_path=http://shop.mydomain.nl&virtual_https_path=https://shop.mydomain.nl&virtual_https_server=https://shop.mydomain.nl&enable_ssl=false&enable_ssl_admin=false&sql_cache=/home/httpd/vhosts/mydomain/subdomains/shop/httpdocs/cache&is_upgrade="] [unique_id "FfiskH8AAAEAAFbblocAAAAE"]

I changed the name of the domain to mydomain and the name of the subdomain to shop
So what to make from all this ?
