during my holidays I upgraded Moodle to 2.5 and installed HotPot-Module. A colegue of mine informed me that after uploading a HotPot-Activity the following error-message appears on trying to start the activity:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [no address given] 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.
Can anybody help?
