You are correct it may not be wordbooker as im having trouble getting thumbnails to show thru other services. Like buttons and share buttons do work on facebook though.
I’ll keep testing things. Let me know if you have any suggestions.
I did notice that in the diagnostic messages it keeps repeating “Looking for favicon.ico in http:….60×60.jpg “
Where favicon.ico changes to other things like gravatar, facebook, plugins etc. but its always looking in the correct thumbnail file.
