Using the customizer I no longer seem able to change the header image that loads when my site loads. Any help would be appreciated. I have tried things like enabling Crelly Slider or the default slider just to see if I can make anything but the current image load and had no luck there either.
I tried to think of any plugins I may have installed since it last worked. I did finally upgrade my .php on my host from 5.6 to 7.2 recently.
