Thanks for your reply but as I mentioned I have inherited this site so I don’t know if the theme was bought from an external source.
However I have found these 2 URLs for the theme and the author in the CSS but neither of them work so where do I go from here? Do I have to start from scratch with a new theme and will that mean these issues will disappear?
Theme Name: Viroshop
Theme URI: https://www.neonthemes.com/themes/viroshop/
Description: Professional eCommerce Theme
Version: 1.5
Author: Viroshop
Author URI: https://www.lifeofstrange.com/
Thanks
