The old version of UBB.threads relied on an old PHP version, which has been removed from the server because of security issues. This required us to upgrade to a newer version of UBB.threads. The new version has a number of significant differences from the old. I've tried to keep FineTunedMac looking as much like it did before as possible, but there are bound to be some quirks and rough spots over the next few days. If you notice anything broken, let me know and I'll try to fix it.
