Support » Plugin: Jetpack by » Sorry it doesn't work

  • I’ve tried everything , deactivate all my plugins, nothing work I still have this error: The Jetpack server could not communicate with your site’s XML-RPC URL. Please check to make sure 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.

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

    If you go to , you’ll see a message saying “XML-RPC server accepts POST requests only.” That’s the correct message. The problem is that there are other elements above the message: an extra blank line. 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:

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

    Once you’ve fixed that whitespace, try connecting Jetpack again; you should be able to. If you can’t, let me know. If you *can*, great!
