To anyone that has come across this thread I found a bit of information. First this is caused by the referral url not matching what gets put in the hidden referral field in the form. What has been the main culprit for me is additional parameters in the url like
?post_id=23 or whatever.
Second the above posted solution will not work. Looking at the plugin code nowhere does that hook get implemented. My guess is that filer was probably in an old version and got taken out and not accounted for.
Unfortunately there’s no clean solution to fix this with out going in an altering the plugin code (which i wouldn’t recommend). The best solution I’ve found is javascript based where you manually change the referral field to match the url.
