 * Yes, same here. My site went down. I turned back to the previous version and 
   now it is working fine.

 * For clarification, the forms themselves are working okay, the bug is in the back-
   end wp-admin. The page for managing CF7 5.5 is returning nothing (unless you 
   have WP_DEBUG set to on)

 * Same here:
 * `:Uncaught TypeError: in_array(): Argument #2 ($haystack) must be of type array,
   string given in C:\xampp\htdocs\xxx\wp-content\plugins\contact-form-7\admin\includes\
   welcome-panel.php:284`
 * I only get these errors on my xampp installations which run on PHP 8, on our 
   business site which is on 7.4 (and online) the update worked fine.

 * Yes, we are on PHP 8.0.11.
    I’ve confirmed that setting the account to use PHP
   7.4 fixes this issue.
