Sometimes this happens to me. For like 5 minutes, it won't allow me to access Bitcointalk.org. Then after that, it starts working again. I think it is just a bug with Bitcointalk. Sometimes it also says that there is too much traffic on the website and that's why I can't access it.
This happen on me as well
I thought only me that occur this problem
edit:
How it looks on my place right now
account tab is missing
I have had this happen to me a couple of times now. If I access Bitcointalk on my phone, this happens. It really annoys me.
