I found a solution: Disable the plugin′s javascript everywhere except on the admin-pages for the plugin.
You might want to make the plugin only load scripts where they are needed?
In functions.php:
//DISABLE WP PRODUCT FEED MANAGER JAVASCRIPT
function products_feed_mananger_dequeue_script() {
//Check if the path of the current page starts with '/wp-admin/admin.php?page=wp-product-feed-manager'
//If it doesn′t dequeue the plugin′s javascript:
$pagepath = $_SERVER['REQUEST_URI'] ;
if (0 !== strpos($pagepath, '/wp-admin/admin.php?page=wp-product-feed-manager')) {
wp_dequeue_script( 'feed-form-script');
wp_dequeue_script( 'data-handling-script');
wp_dequeue_script( 'object-handling-script');
wp_dequeue_script( 'data-script');
wp_dequeue_script( 'feed-objects-script');
wp_dequeue_script( 'feed-meta-script');
wp_dequeue_script( 'feed-handling-script');
wp_dequeue_script( 'feed-html');
wp_dequeue_script( 'feed-list-script');
wp_dequeue_script( 'feed-form-script');
wp_dequeue_script( 'user-interface-script');
wp_dequeue_script( 'business-logic-script');
wp_dequeue_script( 'general-functions-script');
wp_dequeue_script( 'event-listener-script');
}
}
add_action( 'wp_print_scripts', 'products_feed_mananger_dequeue_script', 100 );
