hy folks

i installed cb 1.9. for my new website (use php 5.3. and the newest version of joomla 2.5.) and everything seems to work. but i cant open the config at backend. evertime i try to open this sitei get an error.page with the info, that i have not the right permission to open the site...

very strange - does anyone have an idea, how i can fix the problem...

i am a super-user and have all permissions (as far as i know) -
