XML-RPC Error

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

If you go to https://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: https://codex.www.ads-software.com/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?
