OceanWP Header background image black

Did you try to control this with a function?
And did it stop working recently and is now only showing a blacked out area?
Did you use the hook ocean_page_header_background_image and the function as posted in the OceanWP docs?

Well… Just change your script to give back the image ID instead of the URL:

if ( is_singular( 'post' ) ) {
  // $bg_img = get_stylesheet_directory_uri() . '/img/my-image.jpg';
  $bg_img = 1394;
}

You’re welcome.
Have a nice day!

PS.
Also posted to support hoping maybe OceanWP can fix this, so we can use the image filename/URL again?
