Ultimate Branding throws a 404 error when attempting to save changes to admin menu

I just cloned a site using Infinite WP and for some reason, Ultimate Branding throws a 404 error when I make a change to the admin bar and attempt to save changes. I thought maybe this could be a server timeout but it is only with this setting that I can replicate the issue. I try to refresh and it is as if the page does not exist. I also tried to deactivate the plugin as well as reinstall but no luck.

Any suggestions?
