Error Exponent with manage_themes

Better i explain in english.

It does not happen when I changed the theme by not allowing me to enter management issues, I mean, when I am in Site Settings, and I stand to display the manage themes option appears, but when I click on manage themes I appears error site not found.

Not Found

The requested URL /exponent-2.2.3/manage_themes was not found on this server themes.

Apache/2.2.15 (CentOS)

I don't know that is the problem, everything else works fine

Thank you by your colaboration

This option "Please try using the Exponent menu under Super Admin tools, Extensions, Manage Themes." is ok.

How can i prove if the link on the site configuration page may be incorrect?

Thank you

The link on the site configuration page should resolve to /exponent-2.2.3/administration/manage_themes, not working. Shows the same message that you sent before

Not Found

The requested URL /exponent-2.2.3/administration/manage_themes was not found on this server.
Apache/2.2.15 (CentOS)

but then I will use the alternate route you provided me.

Thank you.

Don't worry. With SEF URLs turned ON (value 1), shows this message

Not Found

The requested URL /exponent-2.2.3/administration/configure_site was not found on this server.

Shown for all, not just management issues but for all site settings, so I leave it off
