 * When I activate the plug-in, I get these errors (local parts removed):
 * **Warning**: include_once(/wp-content/plugins/donation-or-tip-for-woocommerce/
   includes/frontend-ajax.php): Failed to open stream: No such file or directory
   in **wp-content/plugins/donation-or-tip-for-woocommerce/donation-or-tip-for-woocommerce-
   main.php** on line **28**
   **Warning**: include_once(): Failed opening ‘/wp-content/
