I get the below error when trying to enable the LdapAuth extension. I'm stuck using mediawiki version 1.30 because of another extension hasn't been updated yet. Fresh install of this extension. Any known fixes for this one?
PHP Fatal error: Uncaught InvalidArgumentException: Invalid callback provided in /var/lib/mediawiki/includes/config/ConfigFactory.php:108
