My plugin is working on my test site but not my live site

I'm using the popular plugin, Admin Menu Editor (using pro version). This is a great plugin for reordering and renaming the admin panel menu items. The plugin was working great, but now all of a sudden the drag and drop doesn't work. I tried deactivating every single other plugin on my multisite network, and it still didn't work being the only plugin on my site activated. I redownloaded a fresh version of the plugin and that didn't work either. I installed the plugin on my local test environment and it works perfectly. Any ideas on why the plugin isn't working?
