When I add the 'register' item to the nav menu it will add a empty item ('a' tag) to the nav when the user is logged in. Seems like the '$item = null' still triggers the nav to create an item but an empty one. Wired thing is that this empty item sits at a different place ... but it comes and goes with the 'register' item of your plugin.
I am using the 'intent' pro theme.
Is there a fix / workaround? I tried some things myself but I do not know php, only JS.
Thanks and cheers, Alex
