ERROR: Undefined index: PATH_INFO

After upgrading my blog to version 2.5 I’m getting the following errors at the top of the home page only:

Notice: Undefined index: PATH_INFO in F:\Domains\acquiweb.com\wwwroot\blog\wp-settings.php on line 74

Notice: Undefined index: PATH_INFO in F:\Domains\acquiweb.com\wwwroot\blog\wp-settings.php on line 77

I’ve looked at the following threads https://www.ads-software.com/support/topic/164925?replies=6 and https://www.ads-software.com/support/topic/164618?replies=5 and followed the advice given. Firstly I tried cutting and pasting the code supplied but this didn’t work for me at all. Secondly I tried the advice given by djstelios:

Just after the comment about IIS + PHP configuration (line 71) put this check:
if ( isset($_SERVER[‘PATH_INFO’]) ) {

and close the if statement, just above the comment “// Append the query string if it exists and isn’t null”

This works in that it gets rid of errors but brings along another problem where if you click on a blog entry header or choose a category you get a 404 error.

Does anyone have a fix for this at all? As my site current stands when I login I can’t use the admin panel and instead get even more errors:
