Has anyone installed concrete5 version 5.4.2.2 ?

What was the outcome? I just did a one click install on bluehost & when I went to the login page for admin I get errors:

Warning: strpos() [function.strpos]: Empty delimiter in /home6/josiebab/public_html/aikasoul/concrete/libraries/request.php on line 48

Warning: Cannot modify header information - headers already sent by (output started at /home6/josiebab/public_html/aikasoul/concrete/libraries/request.php:48) in /home6/josiebab/public_html/aikasoul/concrete/libraries/view.php on line 833

Blue host says that it's stable but seems not to be. Should I just downgrade to 5.4.2.1?
