Unable to edit Admin Dashboard Menu


I tried to edit my multisite network sites Admin Dashboard (Pages, Posts, Media etc. etc.). I wanted to delete/hide certain menu items from being viewed by my clients on the network.

However, I'm unable to configure the right settings on the right plugins.

I tried on different plugins (Adminimize, Admin Menu Editor and others) but they doesnt work. Could you help me on recognizing the issue is?

My website multisite is: lamanify.com
