 * I had my site in debug mode for some dev work and noticed the following deprecation
   warning with your plugin:
 *     ```wp-block-code
       Deprecated: trim(): Passing null to parameter #1 ($string) of type string is deprecated in .../wp-content/plugins/amazon-auto-links/include/library/apf/factory/admin_page/_model/format/AdminPageFramework_Format_SubMenuPage.php on line 30
       ```
   
 * Not urgent, but would be good if you could address it in the next update.
