Hey grimtooth,
I note in my previous answer I provided instructions on how to adjust the location of the Like Box based upon where you would find it in our most recent Pro release version of the plugin but you might still be using the Free version which has not had the interface updated to match yet so please use the instructions below instead.
I apologize for any possible previous confusion.
1. Go to your WordPress Dashboard – Facebook Feed – Customize – Misc (tabbed page).
2. Scroll down to second section on the page entitled “Like Box/Page Plugin
3. In this section (2nd option) you will see the “Position” option. Using the dropdown arrows, select the position you want the Like Box to be displayed at.
4. Click on “Save Changes” at the bottom of the page.
5. DONE!
