When using "update checked" manually, I receive the following error repeated numerous times:
Notice: Undefined variable: qp in .../feedwordpress/syndicatedlink.class.php on line 747
I checked the code, and it appears the $gp is only defined inside of the conditional check
// line 726
if (!is_null($uri) and strlen($uri) > 0 and $params['add_params']) :
$gp should be declared outside of the block, with a default value (null?) and then set inside this conditional to prevent this error.
This happens on one of the sites I use FWP on, but not another.
