Technical Issue reported by Wordfence

Hi,

First of all, the plugin works perfect and I don’t see any issue as a user – thanks for this! So this topic is not for support. Rather, this is only for feedback.

I received information from wordfence stating there is a tech 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.

First, visit your website (https://flyingdomain.com/) and check for any visible issues. Next, visit the page where the error was caught (https://flyingdomain.com/wp-admin/edit.php?post_type=ycdcountdown) and check for any visible issues.
