[Membership 2 Pro] Redirect to website builder on login Membership 2

Hi,

I talked a couple of days ago to one of your live chat superheroes about a weird problem where on login I am being redirected to bookmark.com. I thought it was because the domain is on a test server and accessed via local hosts, and the guy had the same thing (but arrived at a different website).

However, I've transferred it to my test domain (www.imustardtest.co.uk), which is publicly visible, and I'm still getting the same issue. Please look into this as it's freaking me out!

Thanks,

Arthur
