Okay, so I've removed the option for selecting search in posts/pages so it's automatically set by default. Now results are appearing as expected.
For the $ issue, on the dev site (using an older version of the plugin?) the $ displays. On the current site (updated first post with the URL to current site), if you search “million” then you'll see the issue I'm explaining. Any suggestions?
The only difference between the dev/live site would be the plugin version.
