L10N Issue

Hi,

This plugin’s “Requires at least” is below 4.6. so you need to set a Text Domain in custom-url-to-featured-image.php and it needs to be custom-url-to-featured-image to correctly internationalize your plugin! (see https://developer.www.ads-software.com/plugins/internationalization/how-to-internationalize-your-plugin/#text-domains)

I cannot find the repository of this plugin so I cannot submit a pull request.

The necessary modifications are the following:
custom-url-to-featured-image.php, please add Text Domain: custom-url-to-featured-image to header.
Line 52 should be load_plugin_textdomain( 'custom-url-to-featured-image', false, dirname( plugin_basename( __FILE__ ) ) . '/languages/' );.

admin\class-cust-li-fi-admin.php line 23 should be __( 'Custom Url to Featured Image', 'custom-url-to-featured-image' ),.

Regards,
Alex
