Any ideas why I can no longer post comments? I can type a comment, and the Add Comment button seems to submit, but the page then refreshes without my comment.
I've cleared my temp. Internet files (google suggestion) to no avail. Browser is IE10 on Win 7 x64.
--- Update ---
I was just chuckling to myself. I was about to respond to the comments below, using the Add Comment feature. I feel like Homer Simpson. Anyway, I carried on typing and pressed Add Comment, and guess what... comment lost.
Therefore, I can confirm it's not specific to a particular post. No websense or other proxy in play...
