Hi,
I have a solution to “can’t import demo content”. When I googled “can’t import demo content” your article is one of the first. I couldn’t find an answer from any of the links I googled, but found a solution by myself. Maybe you want to add this to your article? The solution was that my .php didn’t have an .xml reader, longer story here: https://wordpress.org/support/topic/cant-import-demo-content-cant-import-sample-content/
I just want to help the next one with the same problem!
