When sharing a thread to Facebook and the Advanced Forum Rules plugin is enabled the thread title doesn't get picked up by the Facebook Spider. Instead the Forum Title is sent.
i.e If I share a thread with title : Test Post 1 found on Test forum to Facebook.
On facebook it reads :
X Shared Link
Test Forum
www.testforum.com/thread/test-post-1
When it should actually read :
X Shared Link
Test post 1
www.testforum.com/thread/test-post-1
Interestingly enough the blog posts are not affected and display the titles fine.
The spider displays and unknown location in WOL so I take it its been redirected to the Accept Rules page? Or something of the sort.
The workaround is to uncheck the Users Must Accept Rules to : View Forums | View Threads or set the unregistered group in the excluded list it seems to work.
