Anyone have any ideas?

there should be a error message along with that instead of just a line number...

Ah ok there was a line above it saying

Notice: Undefined property: allowpingbacks in C:\Inetpub\wwwroot\home.myplainview.com\blog\blogs\inc\MODEL\dataobjects\_dataobject.class.php on line 461

If you wish to see it for yourself go to

1.9.2 has several updates to the skinning architecture, you can post a request for the update of the skins that need updating here:

There are no more pingbacks in 1.9

The particular bit of code that's producing that annoyance should be in _feedback.php in your skins directory:

if( empty($pb) || !$Blog->get( 'allowpingbacks' ) ) 
...

Just remove anything related to that and you'll be fine.
