SSL and internal server error

Gentlemen,

I am on Fedora 10 with ISPConfig 3.0.1.3 and "host" 3 domains ( something.nl, something.nu and somethig.org )

when I browse to https://www.something.nl or https://www.something.nu first I see a warning about certificates and safety then I click continue to website and the server returns a error 500 ( internal server error )
when I browse to https://www.something.org first I see a warning about certificates and safety then I click continue to website and the server returns a error 404 ( page not found )

When I view the certificates it says: : "issued to localhost.localdomain" and "issued by localhost.localdomain"

Can anyone help me with this ?

 

@ Till,

Will I find the log in ISPConfig ? or will I find it in /var/www/clients/clientx/webx/log ?

 

try searching in
/var/log/ispconfig/httpd/MYDOMAIN/error.log

 

@ Croydon,

In error.log "louwen.nu" there is nothing after June 17 ???
In error.log "louwen.org" there are a lot of errors but I can't see ( don't know ) wich is related to my problem.
In error.log "runningchef.nl" there are the following errors:

Code:

Tue Jul 07 13:09:49 2009 [error] [client 192.168.0.1] SecurityException in Application.cpp:496: Handler not found in configuration
Tue Jul 07 13:09:49 2009 [error] [client 192.168.0.1] Caused by KeyNotFoundException in configuration.cpp:234 Handler "x-httpdphp"not found

I hope all this is helpfull to you

 

Are you using suPHP? If so, what's in /etc/suphp.conf?

 

Re,

@ Falko,

I have enabled suPHP for all three domains in ISPconfig panel, if it works I don't know.

The content of suphp.conf in attached .txt file.

Thank you, again, for your time
Robert
