i've never gone to a member gallery that way, so not sure what used to happen versus what's happening now. when i want to see a member's gallery, i type in my browser's address bar: www.splitcoaststampers.com/go/"Username"
so, to go to your gallery, i'd type:
.
www.splitcoaststampers.com/go/happy2stamp4ever .
edited to add: i just tried your method and it went right to the member's gallery... maybe it was a momentary glitch?
