 * Hi, I’ve installed WP staging with error logs enabled. Haven’t created a staging
   site yet or used any other functionality of the plugin, but when I try to edit
   a post, I get these warnings:
 *     ```

 * Event if it doesn’t seem to be critical, I thought you might want to look into
   this.
 * Best regards,
