I am trying to create a new website using the Wide Range Pro Theme. I have everything done following the guide at the documentation section but I have problems with setting an individual page background image.
It works well with the default inner page background image, but the featured image neither overrides the default one, nor shows if I left the default settings blank.
I have tested it with different picture sizes (more or less 1920 x 1276 px).
I was not able to exactly get the mentioned default size as 1920 x 1276 is hardly scaleable. Is this mandatory for the sttings to work?
