Need help with a github wiki glitch.

Something went amiss with my github thing. I can't edit any of my wikis for my repsitories. About a second after I do any edits I get..

Someone has edited the wiki since you started. Please reload this page and re-apply your changes.

And the save button grays out.

Driving me nuts! Trying to find a solution on the github site is even more frustrating. So, I figured people around here probably know a lot more about this stuff than I do.

Anyone have any ideas?

Thanks!

P.S. Wait! I finally found where I can send a help request to their support thing.
