Hi there,
I see 3 issues with your site, any and all of which could be causing this problem. Issue #3 is the most likely culprit.
1) you are loading jQuery twice, at least on the front-end of your site. I do not know if this is because of your theme or because of a plugin, but in any case, you should only load it once.
2) your theme or one of your plugins seems to be loading an old version of jQuery instead of using the version that comes bundled with WordPress.
It can create multiple conflicts with WordPress and with other plugins like Jetpack. You can read more about it here:
http://wordpress.org/support/topic/troubleshooting-wordpress-35-master-list?replies=4#post-3547424
Try switching to a different theme for a few minutes, and check if that solves the issue; if it does, you’ll want to look for the function loading jQuery in your theme’s header.php file, or in the functions.php file. Once you find that function, you can remove it and enqueue the proper version of jQuery as explained here:
http://codex.wordpress.org/Function_Reference/wp_enqueue_script
If the issue is not related to your theme, please try to disable all your plugins, one at a time, until you find the one that causes the conflict. You can then enqueue jQuery using the method I linked to above.
If you do not feel comfortable editing PHP files, you can also contact the theme or plugin author and ask them to solve the issue.
3) the xmlrpc.php file is not returning the correct response. Can you contact your hosting provider and explain to them that we are unable to access your blog via cURL, which is needed in order to use Jetpack on your site.
You can let them know we tested the following:
1. Check for access to xmlrpc.php via browser:
http://kmdgideas.com/skyhigh/blog/xmlrpc.php
That test returned “XML-RPC server accepts POST requests only.” which is a valid result.
2. Check for access via cURL by running the following command from the command prompt:
curl -i -H 'Content-Type: text/xml' --data '<?xml version="1.0&"?><methodCall><methodName>demo.sayHello</methodName><params></params></methodCall>' 'http://kmdgideas.com/skyhigh/blog/xmlrpc.php'
The cURL test returned the following invalid result:
!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>400 Bad Request</title>
</head><body>
<h1>Bad Request</h1>
<p>Your browser sent a request that this server could not understand.<br />
</p>
<p>Additionally, a 404 Not Found
error was encountered while trying to use an ErrorDocument to handle the request.</p>
<hr>
<address>Apache Server at kmdgideas.com Port 80</address>
</body></html>
Please provide the information above to your hosting provider so that they can correct the server settings to allow cURL access.
