 * Have you updated to 2.1.3?
 * If you disable debugging (WordPress->Settings->WPBook->Stream/Wall OPtions->Enable
   WPBook to create a debug file) or update to 2.1.3 this error should go away.
 * You may need to regrant permissions after the update.

 * I had updated to 2.1.3, and I looked at my permissions and I though they were
   all YES, but when I checked again…the last one (Manage Pages) was set to No, 
   so I redid the permissions and it’s back to working.
 * Thanks…
