Thread:Talk:MediaWiki 1.18/Fatal error trying to upgrade from 1.17.0 to 1.18.2

Running update.php after replacing the Mediawiki 1.17.0 files with 1.18.2 ones, gives this:

Fatal error: Call to a member function getDbType on a non-object in maintenance/doMaintenance.php on line 91

DB is corrupted after this happens. Is this a known bug/feature? The 1.17.0 is an original version, no custom corrections. Boyandin (talk) 01:31, 24 March 2012 (UTC)
