I am having the same issue. I have tried disabling all the plugins, making sure every variation is enabled, no default variation is saved, the product is public. It is only happening when I have a large number of variations. When I save the variation and tick enabled, it unticks after saving.
Thanks in advance
I am also getting this error message when trying to upload the background

Thank you for your fast reply. Where do I add the widget please? I have removed the original images from the media library, selected 5 coloumns and added the images in the footer section. However I notice that there are 5 widget areas in the widgets section named footer. But I can’t work out where to add the blank widget. Thanks
