CMS Made Simple Forums

Hi there.
I need some help with this issue. I installed cmsms on a linux machine (I think that all the permissions where set correctly).
I can update content by clicking the "apply" button - but clicking the "submit" one - causes a server error. changes, that don't requires clicking a button, like changing the template, for example - also causes a server error.
There is no URL assign to my hosting (yet) so there where no dns changes made at this time - (I view the site by updating my PCs host file).
Any suggestions?

Thanks
Shayki

What exactly does the server error say? Post your system information. Post any PHP errors you can find.
