Hello,
as soon as I update from version 3.18.9 to version 3.18.11 my websites crashes on many pages.
In the error.log, I can see the following:
PHP Fatal error: Uncaught TypeError: implode(): Argument #1 ($array) must be of type array, string given in /var/www/virtual/website/html/wp-content/plugins/acf-frontend-form-element/main/frontend/forms/actions/post.php:321"
(...)
