Ladies, I have opened this forum so as to communicate regularly with you on technology issues pertaining to our community. We can all agree that the upgrade backfired - badly. I have personally spent days tweaking and fixing things and still it seemed that everything was not the way it was supposed to. We waited nearly a full version prior to upgrading to vBulletin 4.0. Unfortunately all the nice little things that the new version has came with a price. That price was your retinas (remember all that white when we first opened the new forum?), huge delays on the server, incompatibilities with Internet Explorer to name some. So we are moving towards a new path. We are going to downgrade the forum to the v.3.8 (with some security patches) and that will be the end of it. I do not think we will upgrade any more, unless the new version has something we really need. This last week we have brought in a consultant to work on the web servers. Both servers were upgraded to new software, optimized for our hardware and our forum. Up until last night everything was working fine. However, once we enabled one of the features that would definitely bring the load times even lower, we discovered that there was a problem. There is an area in the forum that uses AJAX not securely. This area will publish to the cache of the web server, cookies from another user. That in effect does the following: User logs in (dimopoulos) Navigation to one page (user becomes randomly someone else - say DLewis) More navigation (user now is SparklingFlame) etc. Some of you have noticed this and created tickets and even tweeted about it. Thanks for that! I was in the middle of more changes so I was not aware of this. The problem was contained by us removing the caching mechanism. We are not going to get the site any faster through that route until we downgrade a version. Once again, thank you for your patience. It sure has been a hell of a month for all of us.
