TypeError: null is not an object (evaluating 'this.currentMenuControl.getMenuIte

I tried checking your link, but I think it’s old and the content has been removed by now. I have been testing the plugin recently and haven’t spotted the error you mentioned earlier:

TypeError: null is not an object (evaluating ‘this.currentMenuControl.getMenuItem

The plugin has had a lot of activity and updates lately. Would you mind re-testing with the latest WordPress and Menu Customizer versions and reply back here if you’re still having trouble?

Here are the related plugins:

• WordPress Beta Tester (backup before installing, and only use this on a test site not in production)
• Menu Customizer

The versions I have been testing with recently are:

• WordPress 4.3-alpha-32784
• Menu Customizer plugin version 0.6-20150615

I’m going to mark this as resolved for now, but if you test again and find the same problem please change it back to not resolved and I will look out for your reply and re-test if needed.
