SQL Error

[getinkshedtears]

I've been using XThreads 1.68 successfully for months on my forum, but recently, when I try to post a new thread, I'm getting the following error:

SQL Error:

1364 - Field 'name2' doesn't have a default value

(where 'name2' is the first of many custom thread fields that is not applicable to the forum I'm posting in.)

I suspect it may have to do with the recent MyBB update, but I can't say for sure that's when it started.

Is there a quick fix to this?  I've deactivated and reactivated, but I'm afraid that fully uninstalling will erase the custom thread fields I already have set up, and which are fairly complicated.
