PageSpeed Admin Panel - Cannot Access via Browser

[sobrenome]

I have followed the PageSpeed instructions to enable the Admin Panel for this Apache mod:

https://developers.google.com/speed/pagespeed/module/admin

<Location /pagespeed_global_admin>
   Order allow,deny
   Allow from localhost
   Allow from 127.0.0.1
   Allow from MY IP
   SetHandler pagespeed_global_admin
</Location>

But when I try to access the Admin Panel via browser, IPS sends an Error 404.

The handler suffers from IPS conflict (pretty URL rewrite).

How to solve it?
