Thanks Chance. Can you please do the following?
1. Try to deactivate all your other plugins except this one to see if it works, then re-activate them one by one and refresh the edit page each time to see if one of them is causing a conflict with this plugin.
2. Try to change your theme to one of the WordPress default themes (twentyfourteen, twentythirteen, etc.), then follow the steps in the FCP plugin video to see if you can get the metabox to appear. If if does, then your theme may be causing the conflict.
It would of course be best to do these troubleshooting steps on a site that isn’t live so users wouldn’t catch a glance of your site with the theme temporarily changed, or plugins not activated. However, if it’s not a high traffic site, you could choose to run through these steps late at night when you’re getting little to no page views, for instance.
Please let me know if by doing any of those steps, you’re able to get the metabox to appear – that’ll help me to troubleshoot the conflict for you and other users. Please also reply with your hosting provider and the version of WordPress you’re running.
Thanks,
Kellen
