ProSites redirect to dev site?

I’m sure you’re sick of hearing from me, but I have a real head scratcher on my hands. From my live site ( the sign up page redirects to my dev site ( I’ve looked through all of the settings and the database and done a text search on the code… nowhere do I find a link to my dev site in any of those places. I have duplicated my live site to my dev site and I would understand this happening in reverse, but I can’t imagine what is going on. I determined that it’s definitely connected to the Pro Sites plugin because I disabled it and was able to hit the sign up page just fine (although there was obviously nothing on it). I’m super perplexed, any help would be greatly appreciated.
