Hello There,
Thanks for writing in! I could not replicate this issue in any of our testing servers. Are you using CloudFlare or may have installed a caching plugin like WordFence, W3 Total Cache or WP Super Cache? Please keep in mind that after doing every updates, always remember to clear all caches when updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
If still nothing is working, would you mind providing us the url of your site so that we can investigate?
Thank you in advance.
