 * After upgrading from 3.1 to 3.4 I can’t do anything after I log in. All I get
   is the following message – Fatal error: Cannot redeclare class Custom_Image_Header
   in /home/content/64/7457464/html/wp-admin/custom-header.php on line 16
 * Please help,
 * Barry

 * Hey Barry,
 * FTP into your site and try deleting the theme that you had active (of course 
   you should back it up first). Sometimes things get quirky when you update.

 * Thank you for your help. We had to uninstall wordpress and then install a different
   theme. It seems that the previous theme was unstable and this upgrade just blew
   it up.
 * I appreciate your help,
 * Barry
