 * When I upgraded my site to PHP 8.3 I received the following Fatal error:
 * PHP Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of
   type Countable|array, false given in <redacted>/wp-content/plugins/subscribe-
   to-comments/subscribe-to-comments.php:1520
   I fixed it by changing the code to
   the following:
 *     ```wp-block-code
       <?php if ( (is_countable( $postlist) && count( $postlist ) > 0) && is_array( $postlist ) ) { ?>
       ```
   
 * but that’s just a patch for the issue of course. Wanted you to be aware so it
   could be fixed in the next version. 🙂
