Add to Multiple Lists-Not working

Using the most recent Firefox (recently updated in the past week), I have been having a problem adding a record to multiple lists. The process works fine (selecting the "Add to multiple lists?" checkbox, drop down of all my lists shows up, I select the pertinent ones, etc.) up until I hit "Add species". In all cases I've also been selecting "Add another species". I then get a white page with the Bubo header, and when I go back to my lists only the list I had initially selected (not the ones from the drop down) has been updated with the record.

Thanks

Oops yes, that's no longer working. I'll have a look at that later. Sorry for the inconvenience!

That took a while to find. Weirdly, some anti-spam software I added recently was interfering with this for some bizarre reason that I don't understand. Removed that, so it is working fine again now. And I'm back to dealing with spam myself again... 

Oh no! Well, thanks for fixing the multiple list issue, curious as to why the spam filter blocked it. I hope a solution presents itself so you aren't dealing with spam continually!
