Tried to reinstall demo content and does not work

Hi I had Sydney Pro installed and then I wanted to change to Perth Pro and installed the demo content and settings but somehow it does not want to work? Is there a way to delete the website and start over again? I cannot access the FTP because it is with Godaddy.

Any advice?

Hi,

You can start over / reset your database with this plugin: https://wordpress.org/plugins/wordpress-reset/ please let me know how it works.

Kind Regards,
