It's the weirdest thing, when I try and use this plugin on a new site hosted on Linode, this plugin hangs, can't get into the settings pages at all. All other Gravity forms pages are available, it's just the CM plugin pages in admin that fails. Have deactivated all other plugins and run it using TwentyTwelve. Also rebooted my Linode slice, but nothing works. Can't access the Gravity CM plugin.
