Can't find FULLTEXT index matching the column list

[jgommel]

Hello all! I recently ported my vBulletin site from 3.6.5 to 3.6.8, but have started to get a few database errors like the one below. My question is, which column am I to be concerned with? Which one do I need to add FULLTEXT to? I can do this thru phpmyadmin, but just want to make sure I'm adding it to the right one. I was thinking it would be 'threadid', but just not sure. I don't want to start changing all my columns to FULLTEXT if I don't need to.

I'm assuming these sudden database errors are the result of a recent mod installed. Short of disabling the mods and troubleshooting each individual install... yikes.
