Whenever i choose one of the default backgrounds (sapphire swatch) in the Theme Designer, it never saves. As soon as i reload the page, it is gone. I even tried making a blank new Wiki, and none of the default backgrounds work. Is anyone else having this problem?
(Also, is there a direct vignett wiki link for the Sapphire Swatch background that i can just pop into the CSS?)
It is generally better to use Theme designer only to customize the background, because it simply allows you to do it faster. Anyway, if you really want to use CSS, I think that the URL of that theme is https://slot1-images.wikia.nocookie.net/__cb1510227740/common/skins/oasis/images/themes/sapphire.png
