DO NOT USE THIS PLUGIN ON A PRODUCTION SITE, OR ON A SITE WHERE YOU NEED TO KEEP THE DATA.
When deleting demo data your ENTIRE WordPress database will be reset, deleting ALL your posts, pages, comments and users. ONLY USE THIS PLUGIN ON A SITE WHERE YOU KNOW THE DATABASE CAN BE WIPED.
If you develop WordPress websites it’s useful to have some demo data in your system while it’s being built. This allows you to check that lists of things are displaying as they should, and that themes are working when they get data in them.
Historically it’s been a pain to add that data in. Either you need to take a backup of another site and use that data, or you need to tediously create multiple users and blogs yourself. No more, not now my Demo Data Creator is in town!
