i have made a region for a shop (/rg define shop) i have then used only one flag, (/rg flag shop use allow) yet i cannot use the signs in my shop when i drop myself? it doesnt display an error message it just doesnt do anything, its like right clicking on a normal sign, yet when i op myself and click the same sign, it works perfectly.
Make sure that the spawn-protection is set to 0 in your server.properties. Also have you made sure that default group has the correct permissions?
