I got this error, when I try to open a new thread:

An error was encountered
Error: Unable to insert search index word matches.

I already tried solutions found here and in google: fix db tables, changing type of search_words table...

Help me, please, my hoster says that their db has no issues, and they can't help me with this error and ask me to post it here.
