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)

Grindlay, yes i agree.

So i stay on 5.5 but dont go to the welcome screen of cf7 until its patched

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.
