Hi, I am customising the Fluida theme and when I go to Site identity >> Header media and try to either add an image or use an existing image nothing happens. Have cleared cache / cookies, deleted and added images, used the images supplied with the theme – to no avail.
That depends on where you’re expecting the header image to change in. Some elements displayed by the theme do not display the header image (even though because we use the same sample image in several locations it may seem to be so).
