 * Hi [@malae](https://wordpress.org/support/users/malae/),
 * Thanks for the report and for using UpdraftPlus!
 * We’ll review this deprecated PHP warning and get it addressed in our future update.
   In the meantime, the warning is non-breaking and won’t affect your site’s functionality.
 * Let us know if you notice anything else!
 * Best Wishes,
   Bryle
