The site has a 500 error with your current version when viewing the wish list page
Seems there is no longer any support, time to ditch the plugin
You define a version variable
if ( ! defined( ‘TINVWL_FVERSION’ ) ) {
define( ‘TINVWL_FVERSION’, ‘2.2.1’ );
}
But in public/tinvwl.class.php you make reference to TINVWL_VERSION which doesn’t exist, it’s missing an F before Version
The latest version is still crashing out
