Fatal error in facebook-wp.php on line 77

I’m having the same problem. And now I can not access the administration page of my blog.

Maybe it’s some problem with my registration application on Facebook, because with another plugin, although it is working, I have a similar message, related to recovery of the secret key.

I’ve checked the key, but is a copy and paste of the key registered on facebook.

Temp fix I worked up..

Fixed with the 1.0.2 update.

thank you very much! had the same issue for my iphone blogs while i added a widget

The likely issue here is that you have another Facebook plugin enabled that conflicted with our plugin. This was fixed in 1.0.2.

Thanks for the report and please take a moment to rate the plugin.
