When I first installed RS (v1.3.28) I was able to add a group but when I selected another item in the admin panel I got a "Fatal Error"message.  After that I was unable to access the admin options soI had to manually rename the (role-scoper) plugin folder and then the admin panel was available again.  I have tried several times now to install it without success. I've removed some other (unused) plugins thinking they may be conflicting.  I have manually dropped the RS tables from my database and reinstalled RS.

I am using WP3.1 and Suffusion theme.

The Fatal Error I get is; (the line number will vary depending on what admin option I try to select).

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 30720 bytes) in /home/stpauls/public_html/wp-admin/includes/plugin.php on line 181

Hopefully someone can help out because this plugin promises to be very useful!
