Internal Error bei der Installation

Hey,
Habe mir einen neuen Server gekauft und alles funktioniert wunderbar, doch dann habe ich versucht mir wbb lite 1 zu installieren, als ich die setup.php Datei aufgerufen habe kamm folgende Fehler Meldung :

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, (email) and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the req

Dachte zuerst liegt an dem wbb ... habe das auf einem anderen Server ausprobiert und alles funktionierte, dann dachte ich es könnte an der .htacess Datei liegen, doch leider funktionierte garnichts und chmod777 habe ich auch gegeben....bin völlig ratlos hat hier jemand vielleicht eine Idee ?

MfG Rayser

PS: Google wusste leider auch nichts^^

Wie ich deinem Post entnehmen kann hast du einen eigenden Server.Ein paar Infos wären dazu nicht schlecht.Was steht in den Logs?

Es ist ein Linux Server hier die Logs:
