I want to install John demo. I’m using Way 1 of your guide
Way 1:
* Install and activate One Click Demo Import plugin from Appearance > Install Plugins. Then, go to Appearance > Import Demo Data and click on the Import button of a demo.
* Install and activate Regenerate Thumbnails plugin from Appearance > Install Plugins. Then, go to Tools > Regenerate Thumbnails and run the plugin once.
But it looks like mess of different demos. Could you help me with it.
