[Plugin: Live Blogging] No right sidebar in 'Write Page' in admin (can't turn on Live

Hi,

I’ve installed the plugin and there are no errors, but in my ‘Write Page’ area, there is no option on the right hand side to enable live blogging as seen in the video.

Any ideas what could be causing it not to show?

Best,
Brad
