Hi Steve,
We have reviewed and checked that you have not purchased our VPNSF plugin to use separately with another theme. So, you have not a permission use the VPNSF plugin separately with other theme instead of BizWalls.
In this issue, you must have to buy the VPNSF plugin (https://codecanyon.net/item/virtual-phone-number-selling-form-wordpress-plugin/19936185) to use separately with another theme.
Moreover, you need to customize the theme to make compatible with a plugin. This is because, all plugins don’t support all themes by default.
Thanks for your understanding.
Best Regards,
ThemeLooks Support Team
