Hi Hawk,
Yes, TC is down ... has been all day for me, too. I'm unable to log in via the admins page, too ... most strange when that happens. It's not the server as both forums run on the same one through the same hosting company ... and the hosting company is okay as I was able to access my forum email account.
I've written to Frederik on this matter ... I only know he is quite tied up working on a deadline for a huge music project. It is mysterious how it just went down ... but with that error message appearing, we know too that it's not a domain thing ... only thing I can figure is that the site got hacked OR Frederik is working on the software.
