WordPress 2.51 and IIS error – Notice: Undefined index: REQUEST_URI in \wp-settings.php on line 81

April 27, 2008 · Filed Under Getting Started 

The original wordpress 2.5 error mentioned in the last post was fixed in the 2.51 release but there is an additional error that crops up. If you are getting an error similiar to the follwing:

Notice: Undefined index: REQUEST_URI in F:\Domains\mydomain.com\wwwroot\wp-settings.php on line 81

To solve this issue you need to edit the wp-settings.php file.  After line 79 or “// Append the query string if it exists and isn’t null” add the following line:
  $_SERVER['REQUEST_URI'] = substr($_SERVER['PHP_SELF'],0);

This error is due to IIS not recognizing ‘REQUEST_URI’

If you don’t want to make the modification yourself you can download the modified wp-setting.php file from here.

    Thanks so much! Is this posted on wordpress.org? It was not an easy fix to locate.
