Still no resolution. Are you sure Aetherth got your message?
I chatted with Aetherth regarding this. We
are looking into it, but it may be more of an account issue than a browser or forum software issue. And no, I do
not know why this is happening.
I will say that if your access to the subforum is blocked, you may have to make sure that you are 1.) logged into the forums on your account and 2.) make sure that you've checked the "Remember Me" checkbox. That may help, though you may not be able to directly see or access the threads in the subforum.
