This just started happening today, and it is causing me a lot of pain. I tried updating the plugin to fix this problem, to no avail, and then I tried to uninstall and reinstall, which made it worse. On the main settings screen for WP-Members, if I make a change and hit update, I get a page that says No Results Found, instead of the yellow bar at the top that says the options were updated. The other tabs work just fine, but not the main options tab. I was trying to change the CSS Stylesheet because things are not lining up on the member edit page, and it didn't work. Now because I removed it and reinstalled it, all of the old settings that were in there before are no longer in there, and I can't change them back either :( Please help!
