Well guys, it
may be fixed. You turned https on w/o telling me, and that caused all sorts of problems. But when I realized what you'd done and both changed the embed code on my website as well as enabled https there, then I could log onto the embedded forum. Then I redirected to my website and that works as well.
I'm not 100% sure the problem has been completely fixed, but it appears to be at first blush. However, my ulcers would have been a lot happier if you'd told me that you turned https on so I could make the needed changes.
I'll do some more testing and report back.
