For folks who would prefer not to add the demo content but still want
the extra custom fields such as Show/Hide Page title.
Go to Tools > Import > WordPress
Install the plugin if needed. Then import the xml file attached at the bottom of this page.
But Help! That still didn't work!
If the previous instruction didn't work, there's an easy solution. Go to 'Custom Fields' and delete the fields in there.
Also (and this is important) completely delete the fields from the Trash.
Then, import the attached xml again from the instructions above and you should be all good.
