Warning: require(./wp-blog-header.php) [function.require]: failed to open stream: No such file or directory in D:\InetPub\vhosts\win.weeatupthecompetition.com\subdomains\wordpress\index.php on line 17

Fatal error: require() [
function.require]: Failed opening required './wp-blog-header.php' (include_path='/') in D:\InetPub\vhosts\win.weeatupthecompetition.com\subdomains\wordpress\index.php on line 17

 

(could be Joomla, Drupal, any PHP site that use includes. So basically all of them)

 

The above is from a generic install from the Application installer. Had I  put this under httpdocs\subdomains there would be no issue. Notice the path is out side the httpdocs folder

 

You shouldn't need to modify any include paths for PHP, I have done this my self, always thinking it was a php.ini issue.  This is not the case.

You only need to make 1 permissions change: Add server\IUSR_someaccount with : "List folder contents" to the directory that is outside of httpdocs. in this case subdomains

 

I went into Plesk afterwards and went to the domain and added then removed "Additional write/modify permission" to see if it would remove my IUSR that I added. It will not be removed via the web interface through editing the domain.

 

 

Technical Notes: Why does this happen; when the windows php-cgi.exe can not getcwd it reverts the current directory to where ever the cgi-php.exe is running in, because it has access to this path it will set the plesk\addtional directory as the current working directory (php-cgi.exe runs under the perms of the  iusr). A simple way to test is to create a php file in the directory your having issues with: then hit that page with a browser

PHP Page:

 

<?php

echo getcwd();

?>

 

This should show the full path to the directory you ran the script in. If it shows: C:\Program Files (x86)\Parallels\Plesk\Additional\[plesk version folder]

Then this is your issue and you can add the IUSR to the root folder with "list folder content"
