Login errors

Getting around 40 per day of these errors on recently repaired forum (this topic) -

I'm not having any problem logging in.  Using .htaccess to force non-www (that was one of the original problems), server is stable (wasn't for a while), no server errors, repair_settings doesn't report any glitches.  Owner is away for couple of weeks, so don't know if members are complaining, but not seeing anything on board.

Probably a bot. I would look up the bot's ip addresses on stopforumspam

That's what it looks like, most ips are from Europe and China, members aren't reporting login problems.
