Hello, we just upgraded from X to Pro today because we need to customise headers for our site.
We have uploaded the Pro theme, activated and created child. When we select Launch we get the menu but if we select either Header, Content or Footer a Green bar moves across the top to the right-hand side suggesting something is loading but nothing does.
I tried it with another browser Chrome instead of Firefox but the same result.
Can someone please suggest what may be wrong?
