Why MODx does not give a 404 error?

There is a site on MODx and links for example site.ru/about the problem is that if you write site.ru/ABOUT open the same page should be a 404-I am error, that is, MODx is not case-sensitive, the way to make it hollow worked fine ? )

In system settings there is a column on the 404 page, there you need to insert the id of the page which will be issued.
She page 404 is, here the problem is that the register address is ignored as an error - Delaney.Tro commented on July 9th 19 at 13:11
