I am getting the following error.
Warning: main(./wp-blog-header.php): failed to open stream: No such file or directory in C:\Inetpub\vhosts\smarthiring.com\subdomains\testimonial\httpdocs\Index.php on line 4
Fatal error: main(): Failed opening required ‘./wp-blog-header.php’ (include_path=’.;./includes;./pear’) in C:\Inetpub\vhosts\smarthiring.com\subdomains\testimonial\httpdocs\Index.php on line 4
Now where do I change the absolute path. In the config file or in the wp-blog-header.php or in the index.php.

Or is it something else???? Please help…
