Problem with Apache 2 and Apache Server

Hi all,


we have installed and customized a Lenya 2.0.3 version, it is so far 
running stable locally (live and authoring) using http://host:8080/lenya/...

When putting it in an apache server   environment, we get everything 
running by accessing the live area like http://www.domain.org
Only accessing the authoring environment https://www.domain.org shows a 
problem, where I can not find any hint to its solution:

Uploading images/assets does not work, after selecting an image, the 
system displays the https://www.domain.org/authoring/index.html without 
any error message in the logs

Please tell me, if you know where to look for a solution



Best Regards

Yehya Mohamad
