Had PopUp Pro working fine - at some point after updates (unfortunately not sure when/which update specifically) it's now not working.
If you visit any of surfersskin.co.nz, kidsskin.co.nz or golfersskin.co.nz and click on the Shop link in the nav it takes you to the relevant shop category on skinalive.co.nz, which uses some custom category header stuff to mimic the site you arrived from.
To explain and re-assure users about the URL change I had PUP set up to show a message explaining the change. Now it just doesn't fire. Settings are as per screenshot attached and haven't been altered since it was working previously.
