maybe I’m an idiot and doing something wrong which is entirely possible, but I added the plguin and code, and I got a menu with only one item in it that says links. If I modify the link text it changes, but that’s it. I can’t get any other menu items on there. Something’s broken!
Looks like you have stumbled across a bug. Try changing the first menu item to something different and see if that helps. I’m intending to do a minor upgrade to the plugin today so I’ll see if I can work out your problem while I’m at it.
