I get this screen after trying to upload an image for a wiki background... It's been like this for several minutes, and I've tried it multiple times.
Could you link the wiki in question? And try to clear your cache, it seems that your browser is struggling to display content
This is a known bug with Theme Designer, I believe.
It is, I recall someone mentioning seeing only the colored background in theme designer, nothing else.
Took you a really long time, does the issue still persists?
Unless FANDOM fixed it, it will probably happen. From what I've seen, it isn't a wiki specific issue.
What do you think?
