Problems when navigating with chrome for iPad

When i surf this site (wayando.com) with my iPad using chrome, the site loads but with these errors before the header:

Warning: session_start() [function.session-start]: The session id is too long or contains illegal characters, valid characters are a-z, A-Z, 0-9 and '-,' in /home/wayando/public_html/wp-content/plugins/wpmu-dev-facebook/lib/external/facebook.php on line 49

Also, if i try to go to the admin panel i get only a blank page with similar errors:
