Open your website control panel . I am using Cpanel , if you are using the same well and good it’s easy for me to explain. Browse through /home/yourdomainname/public_html/wp-includes/load.php path. Now we have to edit load.php file. There is a small change in the 278 line. In Cpanel you don’t have number lines for the code. So do what I say, Press ctrl+f to open search box. Type xmlrpc in the search box. You will be directly taken to the line will we have to edit. You will see the following code.
if ( defined( ‘XMLRPC_REQUEST’ ) )
ini_set( ‘display_errors’, 0 );
this code should be kept in the comments. After adding the comments the code should look like the below..
/**
if ( defined( ‘XMLRPC_REQUEST’ ) )
ini_set( ‘display_errors’, 0 );
*/Save the changes. Now go to dashboard and try to connect with wordpress.com site. You will definitely get connected with the wordpress.com site and both the problems will be solved.
If you test the http://yourdomain.com/xmlrpc.php URL it should display the following message in one line.
XML-RPC server accepts POST requests only.
It should look the small when you open with your domain URL. If all is well then after installing jetpack you will see this pic live with your site. Hope this will help you.
