Hi RomanArt, thanx for your gently and fast contribution.
I edited the "robots.txt" and included "/users" folder (my Monstra version is 3.0.3).
But then I realized that the problem is not "robots.txt", is .htaccess. Because I tryed to access that file and it returned 404 Monstra page.
Every file I put in the root is unreacheable if it is not a Monstra generated page.
I try "mydomain.com/robots.txt" and it returns a Monstra 404 page.
I´ve uploaded an "abc.html" to root and tried to access from browser and it returns Monstra 404 page.
Here is the .htaccess created by Monstra. How can I fix it?
