 * **After updating Gutenberg** on our test environment, Several in-house plugins
   stopped working. It seems that admin-ajax.php is too slow. The Ajax posts results
   in 404, while the data is successfully sent.
 * A cheap solution to fix this, was adding a 200 ok header in our PHP code.
 * But what I can’t seem to fix yet is Network XHR 500 error (PHP code resulting
   into data not sent) in some other forms, unless I deactivate Guttenberg.

 * Are you able to create steps to reproduce and post them to [https://github.com/WordPress/gutenberg](https://github.com/WordPress/gutenberg)?
   I’m not sure why Gutenberg would be affecting `admin-ajax.php`, but if you can
   post some reproducible steps we can definitely try to fix this up for you (if
   Gutenberg is the cause)!
