Yeah, that setting was in a database table that couldn't be imported. Believe me I tried - several times - to get everything imported, but that table kept making this forum "break". It's kind of a long story. I mean, I could have kept on fussing with it for another 3-4 days if I had the time which I don't, and made it all 100% like it was. But it was too long for the site to be down and I made a trade-off. Sorry :'(
The failures were due to lack of understanding, not just mine but the people I tried to consult, who have been doing this kind of thing much longer than I have. None of them had an answer for me. It was trial-and-error guesswork that finally did the trick.
Part of the problem (which is actually a blessing in many ways) is that the server we're on now is somewhat "overhardened" in regard to security. That's coz it gets attacked alot, coz it's hosting sites that some folks would really like to see disappear - like this one. So a lot of the usual fixes I attempted were "seen" by the server as hacking attempts, and it shut me out.
