 * I get the following error code when I try to view install.php in a web browser:
 * > Fatal error: Call to undefined function: is_wp_error() in /var/www/vhosts/andersenstudio.
   > com/httpdocs/wp-includes/functions.php on line 1320
 * Does anyone have a suggestion ?

 * I’d suggest re-copying ALL of the WordPress files and directories to your server
   to ensure you have them all.

 * Thanks for the reply. I will try that.
 * I see the source of the confusion to the duplicate posts is that there are two
   subjects started in my user profile with the same name.
 * Like I said in the other (duplicate) topic I used the Word Press Online edit 
   function within the time frame there-in described, but since the WP-edit-function
   appears to create duplicate topic strings. I will not use that function in the
   future.
