When I try to open the membership module, all I get is a blank page, and it appears that possibly (!) there are problems with member permissions happening also. For example, in the Modzz Sites module, a member can't get the "Add Site" function to work, and I am seeing similar problems with other contribution-based modules.
Any thoughts? How would an admin trouble-shoot this type of problem? I just started up this site a couple of months ago and things were working well previously, (I think).
