Hi,
The link I pointed you to does give some information on how to check for whitespace in your varying files. Try those instructions, and let me know if there's anything that's giving you trouble in particular.
You may also want to contact your webhost about the first error here:
http://www.infagalaxo.com/xmlrpc.php
Warning: ini_set() has been disabled for security reasons in /home/infagala/public_html/wp-includes/load.php on line 278
That is also affecting Jetpack's connection.
