So yeah, this is now a broken site.
If you try to add link in your post - using tags, or if you would tag any user in your post - you will get "It's broken" page. Thing is, your post will be sent... but it will not be shown as last post from the front page, and it even won't bump the fucking thread. Which is a serious problem.
Not only that, but PMs do not send. At fucking all. Even with no links. You will get notice that someone sent you PM, but it won't show in your inbox. And you won't even get notice on e-mail, so you will never know what was in the PM.
This needs to be fixed as soon as possible.
