All you need to do is just install Gourmand WordPress Theme and recommended plugins after this follow recommended actions from Admin Dashboard › About Gourmand.
IMPORTANT: Please remember the Gourmand Light and Gourmand PRO are 2 Plugins what allow you extend Gourmand WordPress Theme core features. This is a better way to upgrade your theme with extra features without lose current settings and any data. Also these 2 Plugins work well with any Gourmand Child WordPress Theme.
So the Gourmand Solutions are a Better Choice for your website and your choice is greatly appreciated!
I have installed Gourmand lite as well as the Gourmand theme.
As soon as I activate the plugin the theme’s customize page no longer loads correctly.
The wizard works but the customize page is now blank and there are no options on the side bar other than “widgets”.
