    When I install jetpack and try to connect to wordpress.com, I get this error:

    Error Details: The Jetpack server could not communicate with your site's XML-RPC URL. Please check to make sure http://ncfmaryland.org/xmlrpc.php is working properly. It should show 'XML‑RPC server accepts POST requests
    only.' on a line by itself when viewed in a browser and should not have any blank links or extra output anywhere.

    I tried lifeofinterests solution in this post http://wordpress.org/support/topic/jetpack-showing-error-xml_rpc-32700?replies=19 and it didn't work. Any help would be appreciated.

    It looks like there is a misbehaving wp-config.php, plugin, or theme on your site.

    If you go to http://ncfmaryland.org/xmlrpc.php , you'll see a message saying "XML-RPC server accepts POST requests only." That's the correct message. The problem is that there is an extra space above the message. This extra space is annoyingly important. It suggests that some plugin, theme, or wp-config.php file in your WordPress has extra "whitespace" (new lines, spaces, tabs, ...) before the first <?php in the file. This problem is another symptom of a more common problem: the "Headers already sent" problem: http://codex.wordpress.org/FAQ_Troubleshooting#How_do_I_solve_the_Headers_already_sent_warning_problem.3F

    Can you check your wp-config.php, theme files, and plugins for such whitespace?
