 * Going to my site, [The Couth Hillbilly](http://www.crawfordharris.com), 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
 * 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 267
 * 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.

 * You are a lifesaver (not the candy). It took several repetitions. Each time I
   corrected one line I received an error on a line futher down. Even though I am
   completely unfamiliar with php there was no problem other than having to repeat
   the procedure.
 * It appears that the entire problem was caused by the plugin wp-visitors, which
   I had installed just prior to upgrading.
 * Again, thanks.
