Cannot publish or save changes on the posts – no error

Hi,

We’re trying to update and publish posts but isn’t working. It doesn’t show any error, it shows a message that “save in drafts” however, it doesn’t save any edition either. Screenshot here https://ibb.co/Gn8Qk4m

We’ve tried to use the plugin heath check to try with the troubleshooting mode, but it also shows only the save in drafts message and don’t work on publishing anything.

What else can I do to solve this problem?
