Fatal error: Call to a member function get_option() on a non-object….
Any idea what could cause this error:
Fatal error: Call to a member function get_option() on a non-object in .../wp-content/plugins/admin-columns-pro/classes/filtering/classes/model.php on line 858
I get this when adding a column with yes/no editing capability to https://ecomento.de/wp-admin/user-edit.php for a user meta field that can have the value “1”, “0” or be empty.
