I enabled everything inside the Advanced settings except for the one setting that WPBook documentation says to disable. Sorry, I can’t remember the exact settings I enabled/disabled, but pretty much enabling everything seemed to work. (minus the one that WPBook says to disable.)
Actually, I just figured it out. I need to enable a bunch of things inside the advanced settings of the Facebook App. Thanks.
I too am having this issue. Inside Facebook it just keeps refreshing constantly. All other plug-ins disabled.
