thanks for your reply.
i increased the php memory but the problem is stil there. i am not able to save that stuff more than one time. every time i make a change all is gone.
it would be the best you give me a mail adress where i can send you some temp login information so you can try it by yourself. here is a link to the page but you want see too much. http://tinyurl.com/k92h5da
To make it more clear i did following screenshots:
2) filled the layout with content
3) that is what it looks like after i hit the publish button. all is gone!
come on guys.. i really need to know what i can do to solve this. is this possible or is just one layout at once possible?
