Oops, just discovered can’t post comment in IE

Wow, I have a lot of blogs and I need to get on myself to more regularly check them in IE. Geez. Anyway, most of us might not think to leave comments in browsers we don’t use, and this could be why comments have dropped dramatically.

I get this error when trying to post a comment,

“This file cannot be edited on its own.”

I’d say this is urgent, can anyone offer help?
