Interesting. I haven't seen this error. Can you each tell me what browser and version you are using? I switched the site to use compressed output when delivering pages, which has sped the site up and has dramatically reduced the bandwidth used. Most browsers should handle this.
The fact that it works on a retry suggests it's not a "deep" issue, but I'd like to figure out if this GZip function is what is doing it. It's quite a common feature, so I'd be surprised it was causing a major problem, but it is the only change I've made to how the site delivers pages in the past week or two.
Atticus, the bridging mechanism between the front site and the forum is quite clunky. When you change your e-mail using Your Details on the front page, it doesn't always update the one stored in the forum part, and vice versa. Check your profile in both parts of the site to be sure they are both set to the one you want. I'd do it for you now, but I don't know if you updated via your forum or front end profile <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt="

When the site migrates to Beoir there will be a considerably better mechanism to handle this.
