 * Hello,
 * When using PHP8.0, login to the backend (current WP version) doesn’t work, this
   error shows up in the log:
 * `2022/02/17 08:50:00 [error] 3485756#3485756: *82132 FastCGI sent in stderr: “
   PHP message: PHP Fatal error: Uncaught TypeError: Cannot access offset of type
   string on string in /var/www//wp-content/plugins/countdown-builder/classes/countdown/
   Countdown.php:400
    Stack trace: #0 /var/www/wp-content/plugins/countdown-builder/
   classes/countdown/CountdownModel.php(18): ycd\Countdown::getPostSavedData() #

   Countdown::getCountdownsObj() #4 /var/www/wp-content/plugins/countdown-builder/
   assets/js/Js.php(41): ycd\Countdown::shapeIdTitleData()
 * Maybe you can reproduce this issue? I have it on twi different web servers. Just
   switching to PHP7.4 makes it work again.
