 * This is the message I received by email from WordPress:
    ====================
   ==================================== 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, Shopp.
    <snip
   > When seeking help with this issue, you may be asked for some of the following
   information: WordPress version 5.5.3 Current theme: Rover (version 1.0.0) Current
   plugin: Shopp (version 1.4) PHP version 7.4.11
 * Error Details
    ============= An error of type E_ERROR was caused in line 493 
   of the file /home/rover407/public_html/wordpress/wp-content/plugins/shopp/core/
   library/Markdown.php. Error message: Uncaught Error: Call to a member function

   ======================
 * I haven’t done any markdowns so haven’t seen the error, but felt I should report
   it.

 * Oops. I noticed that I missed removing the number 407 in one spot in the email(
   I was removing them all manually from the email – my bad). That is not the issue.
   The bad call is.
