Yes, after I installed Jevelin, I ended up with 1000+ pages, all empty, all published. All I’m trying to do is make a Homepage for Blog. That’s it! But the Home Blog is not listed as a template. This is a mess!
Screenshots of my 1000+ pages below. Yes, my “Pages All” has 84 pages of Jevelin empty pages.
I hope you are well today and thanks for posting here.
Not sure what you did that caused to generate these pages but from your shared screenshot it seems the pages are not created by theme demo content but something else.
I have answered in your following topic how got create blog page.
