Fatal Error

When I try to edit a page, I get the following error.

Fatal error: Call to undefined method FW_Option_Type_Form_Builder_Item_Calendar::get_item_localization() in /home/allthingsmidmo/public_html/staging/wp-content/plugins/unyson/framework/extensions/forms/includes/option-types/form-builder/class-fw-option-type-form-builder.php on line 52

I went back and deactivated other plugins, etc, but haven’t had any luck fixing the problem. Any help would be greatly appreciated.
