First, the example in our code is wrong with that tag name. Please change SCFacebookPlugin to SCFacebookPagePlugin. After changing that tag name, I put those two easy-tags on my test site and they both rendered the page plugin properly.
Second, check to see if you have a Social Tag Admin Key value set in the JFBConnect > Social > Misc tab. If so, you will need to add it to the tag. For instance, if you have key=abcd, then your tags would be:
{SCFacebookPagePlugin height=200 width=200 href=http://www.facebook.com/SourceCoast show_faces=true hide_cover=false show_posts=true key=abcd}
{JFBCFan height=200 width=200 href=http://www.facebook.com/SourceCoast show_faces=true stream=false hide_cover=false key=abcd}
Try these suggestions and let us know if they help. If you're still having problems, we can take a look at your site.
