Database Error Number: 1191 (vBulletin 3.8.0)

[yotsume]

I stated that I did that already in bold red text in my initial post. That solution does not work. A number of people have suggested that in other posts and all reports have failed using that as a solution.


I have tried a number of solutions but none have worked so far.
I tried:
-Changing the search type (didn't work)
-Emptying and Rebuilding Search Index (didn't work)

I am going to need direct database help with this one...

AS A TEMP FIX: I turned off all settings that search for similar threads (as a temp fix) and one search for similar threads hack. Now I can post a new thread to my forum and not get any database errors.

So any ideas on what I can do please to fix this error in my database so searching for similar threads can all be turned back on???
