Hi,
Not sure WHAT has happened, but the home menu, THE ARENA, is not working correctly on any of the sites.
If the user clicks from one menu to another, and then click on THE ARENA, they are getting the Charm login screen. They aren't being logged out, but there is something that has changed with the menu.
I've tried to fix it, but may have made it worse.
The main/live sites are the priority her:
Masquerading.com
MasqueradingPets.com
MasqueradingDating.com
