Please Help Pro Sites don't let me Save Settings!!! I get a 404 Error!

I Migrate my multisite to a new VPS same domain! and now when I want to save the changes in Pro Sites gives me a 404, I tested in my test site and I could recreate error with the theme Twenty Fifteen and only pro sites installed. Other thing also I have the same error when saving changes in Ultimate Branding I will allow access to the test site for that developers can check my site please. I have one week trying to find this error.
