Hello I am using Google Page Speed Service on my blog, some time I get this error "Fetching of original content failed due to Proxy Publisher Failure: TIMEOUT" from Google PSS faq I got a piece of code which I need to add in wp-config.php here is the code // The real client IP is the first IP address in HTTP_X_FORWARDED_FOR if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])) { $ips = explode(',',$_SERVER['HTTP_X_FORWARDED_FOR']); $_SERVER['REMOTE_ADDR'] = $ips[0]; } So here is my question where to add this code I mean inside opening tag or outside opening tag of wp-config.php
