Thanks, b4 team, for the quick bug fix.

The site was down but back up quickly. I searched for the keywords indicated in the mybb error message and found this article.

I don't know if it's relevant to the server configuration used here, but thought I might as well pass it along in case there's some useful clue in the article.

It was definitely a very quick fix! I'm grateful.

I had never seen this bug before on bring4th.
Lets hope it's just a glitch, table corruption can occur with an unlucky power surge or network failure.

Indeed, well done on the quick fix.
