On some servers that run PHP as a CGI process and do not support the PATH_INFO server variable, this may allow you to run your site without forced query strings.
Open your index.php file and find the line:
$path_info = (isset($_SERVER['PATH_INFO'])) ? $_SERVER['PATH_INFO'] : @getenv('PATH_INFO');
Replace it with:
$path_info = (isset($_SERVER['ORIG_PATH_INFO'])) ? $_SERVER['ORIG_PATH_INFO'] : @getenv('ORIG_PATH_INFO');
If you are already using Forced Query Strings, remember to disable that option in your system preferences, and change the $qtype variable in the index.php back to ‘0’.
Users have reported that with GoDaddy Linux shared hosting, as well as BlueHost and Siteground, ORIG_PATH_INFO is supported.
This does not work on Verio’s shared servers as best as I can tell.
This has been confirmed as a fix on 1&1;Internet’s Shared Hosting Linux accounts.
