Not sure if anyone else was having this problem, anyway here it is: whenever a subscriber logged in they would be redirected to their profile, however if they clicked onto the dashboard tab it would spit out the following error message
You do not have sufficient permissions to access this page.
I believe that in Internet Explorer it was giving a internal server error :|
I managed to fix this by installing the role manager plugin (yes it seems compatible with wordpress 2.5), i then used that plugin to change the user level of my subscribers from 0 to 1.
Now its fixed :)
