[] Your Site is Experiencing a Technical Issue

Howdy!

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, Email Verification / SMS verification / Mobile Verification.

First, visit your website (https://www.jackbite.com/) and check for any visible issues. Next, visit the page where the error was caught (https://www.jackbite.com/wp-admin/edit.php?s=&post_status=all&post_type=shop_order&_wpnonce=488a7016fd&_wp_http_referer=%2Fwp-admin%2Fedit.php%3Fpost_type%3Dshop_order&action=71&m=0&_customer_user=&paged=1&ddwc_meta_noncename=2fc2c704eb&12334=-1&ddwc_meta_noncename=2fc2c704eb&12335=71&ddwc_meta_noncename=2fc2c704eb&11864=-1&ddwc_meta_noncename=2fc2c704eb&12332=71&post%5B%5D=12348&ddwc_meta_noncename=2fc2c704eb&12348=-1&ddwc_meta_noncename=2fc2c704eb&12336=-1&ddwc_meta_noncename=2fc2c704eb&12337=-1&ddwc_meta_noncename=2fc2c704eb&12338=-1&ddwc_meta_noncename=2fc2c704eb&12339=-1&ddwc_meta_noncename=2fc2c704eb&12340=-1&ddwc_meta_noncename=2fc2c704eb&12342=-1&ddwc_meta_noncename=2fc2c704eb&12343=-1&ddwc_meta_noncename=2fc2c704eb&12344=-1&ddwc_meta_noncename=2fc2c704eb&12345=-1&ddwc_meta_noncename=2fc2c704eb&12240=71&ddwc_meta_noncename=2fc2c704eb&12241=71&ddwc_meta_noncename=2fc2c704eb&12242=71&ddwc_meta_noncename=2fc2c704eb&12246=-1&ddwc_meta_noncename=2fc2c704eb&12251=-1&ddwc_meta_noncename=2fc2c704eb&11474=-1&action2=-1) and check for any visible issues.
