 * The following PHP warning is flooding my error logs:
 * [23-Mar-2023 20:46:48 UTC] PHP Warning: Array to string conversion in /wp-content/
   plugins/gravityforms/includes/addon/class-gf-addon.php on line 667
 * 
   I also ended up with this critical error:
 *     ```wp-block-code
       [22-Mar-2023 02:24:28 UTC] PHP Fatal error: Uncaught Error: Cannot use object of type WP_Error as array in /wp-content/plugins/connector-gravityforms-mailerlite/class-gf-cgfm.php:875

       ```
   
 * Gravity Forms believes the two may be related and suggested I contact you. Can
   you help me figure out the issue?
