Vantage: Login Error for Users that Use Wrong Username or Password
When a user tries to login to our Vantage theme, if they use the wrong username or password, they are not shown any error messages, but rather the page reloads with a fatal error. Page loads with header intact, but with this message:
Fatal error: Call to a member function add() on a non-object in /home/ssicommunity/directory.saltspringexchange.com/
wp-content/themes/vantage/includes/controllers.php on line 699
Any idea what is causing this and how to fix it?
