So on my forum @ seriousbloggers.com, a member (regular, registered) posted a topic, I then replied and then they attempt to reply and couldn't do it. No error, no message, just hitting reply and nothing happening. The forum is the latest version as of today and was the product of a fresh install. The weird thing, the user can reply to other posts. The user reports that using firefox and chrome is when this issue would happen, when they use IE, its fine and they can post. Odd huh? I use firefox myself and have absolutely no issues on my end at all. I checked permissions, settings and made sure I didn't thread ban the user by mistake - all appears normal!
