I have recently updated Moodle to 3.1.1, unfortunately it seems that the essential theme has caused an error which is preventing the LDAP connections working correctly (at least I hope that is what is causing the error). I understand that essential is no longer supported and have installed adaptable, however I get a Fatal Error: Call to undefined function theme_essential_get_setting() from line 37 of essential renderer.php when I try to change the theme using the theme selector. Which field in the database do I need to change to set up adaptable as the theme rather than essential?
As a point of note I have tried deleting essential and then going to theme selector and get the same error noted as coming from essential's renderer.
