"Role based access" broke admin console?

I just tried to activate “Role based access to administrator area” and now my admin console seems to be locked. I keep getting “Access Denied” errors on every page past the Home/Statistics page (and can’t get back to the settings to fix it!)

Am using CS-Cart 1.3.3 on Apache. I am logged in using the main admin account and I don’t know why it won’t give me access - it’s the only admin account we use.

Any help would be appreciated.

EDIT: I found the value in the DB and changed it back to “N” which reset my access (so I can get in now) but how can I set it up so that I can have staff user levels if checking the box locks me out of the site? Is there something else I need to set to make this work?

Thank you
