Internal Server Error

Buenos días, estoy preocupada porque al intentar abrir interfaz me aparece esto: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, webmaster@vkoha 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 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request. Apache/2.2.9 (Debian) PHP/5.2.6-1+lenny4 with Suhosin-Patch Server at 1024.bepe.ar Port 8080 Que ocurre? es que no puedo utilizar nada. Gracias Vanesa
