Ok, so I have discovered that a certain thread title posted by one of our site's admins caused me to be unable to reply to that thread, unless I use IE. Chrome and Firefox just ignore me pressing the reply button, no matter what message I enter. I recreated the problem in the test forum here: http://xenforo.com/community/thread...te-the-small-one-on-the-sponsored-area.44306/ Is anyone else able to reply to this thread? This could be a browser add-on issue, but as I mentioned, I tried it in two different browsers where it didn't work, and one where it did. NEW: Chrome in incognito mode DOES work.
