And the difference is?
I just found it odd that:
A: I was sworn at for posting the problem.
B: I didn't have the problem until this week. Most seem to have had theirs in December, but when I check my Bing tools my December submissions were OK. It's only now that I'm having the issue.
Still getting this error. Oddly, I don't get any error with any other site than the one using Xenforo. (I have a Vanilla, Wordpress and PHPBB site and none of them get an error submitting site maps to Bing.)
