My custom headers won't work on my theme.
I know it's supported by this theme(vertigo) and was working perfectly fine.
I tried to remove it, by clicking ''remove header image'', to see what it looked like with no header, but now I can't put any of my headers back on.
I can still upload custom headers and preview what they look like, but I can't apply any changes.
What should I do?
The blog I need help with is neonlanterns.wordpress.com.
