Dear Volksschule Reinsberg,
We dont know what the schulführer is, we can not have any idea what is bugging you, unless
you provide the information.
If the schulführer is a selfdeveloped application, contact the person who developed it for you.
this List is the developer List.
Some Topics must be provided by you to get worthwhile replys:
-post your issue in english
-post eGroupware Version and (if possible - Revision)
-State the module, where you experience the problem.
-State how a developer may be able to reproduce the error.
-Check your WebServers error Log for errors during the timeframe in question.
If any - provide this information
Have a nice day
Leithoff, Klaus
