When I try to search for new posts, I keep getting the “Database being upgraded” error message. Is anyone else seeing this? Is this a glitch that’s being worked on?
I’ve been using it all day as usual and no problems.
i just used it to find your post near the top.
Try clearing your cache.
Hmm, yup, that did it. Isn’t that funny - the last thing I would have expected to be caught in an old cache is the New Posts search. 
ETA: Thanks, by the way - never say this is a thankless job.
