How to Implement
1
Locate your functions file
Open your active theme's folder and find functions.php. Alternatively, create a site-specific plugin.
2
Customize the Array
Change ['product', 'event'] to the slugs of the Post Types you want to target.
// Example for a simple 'Portfolio' site
disabled_types = [ 'portfolio_project', 'testimonial' ];
disabled_types = [ 'portfolio_project', 'testimonial' ];
