It was all looking so good on Saturday too, so it's a shame that you've had to take everything down after all those changes. As Killersquid says though, you've got to do what you've got to do to identify the server issue. I don't envy you.
Certain boards which never used to add to your post count now seem to, so that's something else you might want to add to your check list as you gradually start adding things back in.
A couple things I've noticed which I've noticed which might be helpful, in order to prevent Kindred having even more questions asked of him:
1. If you can't see the signatures of other users, then this is not a fault, you just need to adjust your settings (the reboot seems to have set not being able to see users' signatures as the default setting).
2. To return to the thread you've just posted in, you also need to amend your settings, as this has been deactivated by the reboot.
To find your settings, you go to Profile > Account Settings > Modify Profile > Look and Layout > (un)tick the relevant boxes.
