Can't use the search tool

For some reason, I can’t use the search function. I’ve tried several different time spans and lots of different search words, but I always get the “sorry, no matches” page.

I’ve even tried to use a search terms I see is currently on the board, but same thing.

What’s wrong?

you are specifying the correct forum, aren’t you (the default is ATMB - this forum)

Sorry, it works now - for the first time in several days. I don’t know how and why, but it does.
