My new blog works fine, except when i add pages, i get an error 500 (on the admin page as well as in the actual blog). Same thing happens when i want to attach a file to a post. The only thing i can do to get it all running again is log on to my hoster's (german provider "strato") admin page and set it to interpret every php-file with php 5.1.1 - which it is already set to from the last time i set it to 5.1.1. - i don't even change anything, i just press okay in the php config.
I totally don't understand this, but then again, i have no clue of php and mysql. Can anyone help?
Thanks a lot!
