Reply from FT Support:
Thank you for reporting!
We've been aware of the issue and currently investigating - but I must be open with you, it will probably take a few more days before we can address it as we're in the middle of firing up FT STEM and I can't redirect my attention elsewhere until completion. The forum is very dear to us, I personally hate seeing it in shambles, and we know the community is affected. I can promise this is very temporary, we'll get it back up and running smoothly, soon.
Thank you for your patience, and for your continued support!
All the best,
Robert
