Ha! You are right! So the reason is not the changes done to my ftp-server, but the changes done at the forum?
Then this is a general issue. There are many dead links in here.

If I change to http:// loosing the "s", all my dead links are suddenly alive again.

But then I am logged out, and not allowed to log in again.
It becomes a sort of "view-mode", where you are like an un-registered visitor, allowed to look, but not allowed to comment.

Is there a way around that you think?
