First, I would like to apologize to you and everyone else who faced this problem. The reason for the errors was not related to the forums themselves. Over the last two days we faced a problem with our server configurations. Approximately an hour after you made this post, we managed to completely resolve it so you shouldn't get errors any more.
I want to thank you for the patience and understanding and hope this issue will not leave a negative impression on you. We'll do anything possible to avoid similar situations in the future.
