1- I have triple checked the installation instructions and I am sure I am not missing anything including Moving admin-menu-editor-mu.php, from the “admin-menu-editor” directory to “mu-plugins” directory.
the menu for plugin is just not showing up under setting’s panel both for multisite and single site installations, I don’t get any kind of errors though (I am running WP 3.3.1), I also tried deactivating all other plugins.
2- An amazing thing does happen, Later when i try to install the plugin thru add-new option from browser [without deleting the old plugin files from “/wp-content/mu-plugins” folder.] It says the plugin is already installed, this indicates Plugin for Multisite installs sucesfuly but its Menu is just not showing up in the settings panel.
I have contacted the Author though, btw thanks for your quick response 😀
