Hi Mikko!
I was updating to the new version of relevanssi, and although on a website went smoooth, on another i got this error message:
[You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''typeitem' ('type', 'item')' at line 1]
ALTER TABLE tableprefix_relevanssi ADD INDEX 'typeitem' ('type', 'item')
