Recently we migrated the mysql database and changed the passwords of some of the users. We configured the new passwords as described in the configuration reference, and everything seem to work alright, but the daemon log is continuously writing this error:
[15-Mar-2016 13:26:29] PHP Fatal error: Call to a member function establishConnection() on a non-object in /opt/phabricator/src/applications/search/engineextension/PhabricatorFulltextIndexEngineExtension.php on line 73
I have tried to trace the php to see the origin of the error, but I'm just useless with PHP.
