Well, nothing works. Loaded the demo data and would like to edit stuff one by one instead of starting from scratch but anything I change, once i save & update it'll  just go back to what it was previously. Tried to change the logo by changing it on the web interface but it doesnt work. Had to overwrite it via FTP. but thats the only change that i manage to update. 

Thank you.

sorry, the mod security for my domain in cpanel was activated. its all good now.
