Going to my site, The Couth Hillbilly, it appears correctly. I try to log in and the following shows above the login graphic:
Warning: Cannot modify header information - headers already sent by (output started at /home1/xxxxxxxx/public_html/wp-content/plugins/wp-visitors/wp-visitors.php:12) in /home1/xxxxxxxx/public_html/wp-login.php on line 255

After login the screen contains only the above warnings plus 4 others for various lines in pluggable.php. There is nothing to allow me to access any of the admin area.
