Content Module cannot be changed

I just installed the Bunsiness-Edition - I already had the free edition running before. Now I want to change the Content Module with the carusel option enabled. When saving it turns back to non carusel, but says that the save was successfull. Also any other modification to that module, has the same effect - nothing changes. I also tried to make a new module, but the same problem appears.
Any hints?

Hi
no I get no error. I yesterday recognized, that I cannot make any changes - not even to generell setting of the shop. Always the same effect. It tells me that it has been stored correctly but the changes take no effect - the old settings (before saving) appear. I activated the debugging mode, but do not know what to do with it. So you want access to my backend? I can give url and username/passwor - but not here in public. Do you have an email at which I can send this infos?

as requested I sent you an email with the login informations.

hi and thanks for the reply

you are right it works fine with safari. I usually use google-chrome and it worked fine as long as I worked with the free version of hikashop - the busniess version works not correctly with chrome. It's some kind of strange - every other components (not hika) work perfect under chrome! I think you haven an issue on that.

kind regards
