So based on the error I am getting below I am guessing that there is an incompatibility with the gd-star-rating plug in
I get the error when I open the editor, it shows up in the FB Connect publisher area and the rest of the editor crashes.
Fatal error: Call to a member function render_article() on a non-object in /home1/ucanyonc/public_html/wp-content/plugins/gd-star-rating/code/class.php on line 268
If I deactivate the publisher the error goes away and I can still edit.
This only happens on pages where I specifically insert calls to gd-star-rating, all other pages seem to work ok, though the publisher button does not show up, but the editor doesn't crash.
