After the update last night, I now get this error:
Fatal error: Call to undefined function relevanssi_get_post_type() in /wp-content/plugins/relevanssi/relevanssi.php on line 1257
But only on certain words, which seem random. For example "growth" doesn't error, but "transit" does. The install is straight out of the box, as it were, with no extra stop words, etc.
