If you have a custom theme and have modified either _columns_2.html or _supporter_nav.html, you can apply the fix by wrapping the like box snippet in a div with a new class called "fb-like-box"

Sample Embed Code:

<div class="fb-like-box"><fb:like-box href="{{ site.broadcaster.facebook_page_profile_url }}" width="240" show_faces="true" stream="false" header="false" colorscheme="{{ site.facebook_colorscheme }}"></fb:like-box> </div>

Custom Widths:

If you want a custom sized like box less than 292px wide, you can also wrap the embed code as shown above, but modify the width value to whatever you'd like both in the embed code, and by adding this class to the theme.scss:

.fb-like-box iframe { width: XXpx !important; }

You can also implement a different solution, like others mentioned here.

Remember: the FB like box needs to be updated in both the columns_2.html (view for logged out users) and the _supporter_nav.html (view for logged in users).
