MichaelH — I changed the values in the wp-config.php file because they were “example – change the value” fields. And I changed the values to my URL, user name, and password. I have validated this several times that they are correct.
The information here is consistent with what I thought was the problem. The things that need to be checked are the server name and the valid content in the fields mentioned above. Does it make a difference in which folder wp-cofig file is? public_ftp, sem-pro, wp-content, wp-includes, or www wp-admin is currently contained in public_html, sem-pro and www and the wp-config.php is in public-ftp, sem-pro, and www.
