[Plugin: WPBook] Storys Plubished to my personal wall not the Page

I’ve put all the required info in the settings for this plugin, and it has been working fine. However another editor recently made a post to the blog and it was published on my wall, but not the page I’ve setup.

This has worked fine in the past, I’m not sure what’s up now though.

I do get this error on publishing:

Fatal error: Access to undeclared static property: Facebook::$CURL_OPTS in /home/fhlinux210/m/mumc.me.uk/user/htdocs/blog/wp-content/plugins/wpbook/includes/publish_to_facebook.php on line 37

But on refreshing and resubmitting the post it goes though to the blog and to my wall but not the fb page’s wall.
