I installed WordPress directly to http://whynaturally.com and am now trying to change the Website URL to http://whynaturally.com/elsewhere for security purposes, leaving the Site Address as whynaturally.com. I have tried following the step-by-step Codex instructions at http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory but am confused about which changes I need to make in FTP. I am using DreamHost as my host, and I have tried the suggested changes to both the index.php file and the wp-config.php file, but neither will allow me to view my site correctly. I cannot make changes directly in WordPress either, because when I try to visit either http://whynaturally.com/wp-admin OR http:whynaturally.com/elsewhere/wp-admin I get the following error message:
"Warning: require(./wp-blog-header.php) [function.require]: failed to open stream: No such file or directory in /home/raceng/whynaturally.com/wp-admin/index.php on line 17
Fatal error: require() [function.require]: Failed opening required './wp-blog-header.php' (include_path='.:/usr/local/lib/php:/usr/local/php5/lib/pear') in /home/raceng/whynaturally.com/wp-admin/index.php on line 17"
Somehow, when I visit both http:whynaturally.com and http://www.whynaturally.com/elsewhere/wp-login.php, I am able to view the site and click on the links, but the formatting is not right and I still cannot access my WordPress dashboard or admin features. How do I get my site to look and function normally again? Thanks in advance for any help!
