Header Featured Image Options gone after upgrading to WP 4.5
Catch Kathmandu Header Featured Image Options gone after upgrading to WP 4.5. Theme works perfectly on previous WP version, however options under "Header Featured Image Options" disappear after upgrading, the only available option is "Custom Header" and the button [Click Here to Add/Replace Header Image], which takes you to the (useless) WP customizer.
Please help.
