Yes, Royal Mail changed their tracking link again in June 2014. We don't know why they didn't just set up a redirect from the old URL to the new URL, but well, their business is shipping. The old URL used to track a shipment was: http://www.trackcourierstatus.com/track-royal-mail?trackNumber=#TRACKINGNUMBER# The new URL used since June 2014 to track a shipment is: http://www.trackcourierstatus.com/track-royal-mail/track-your-item?trackNumber=#TRACKINGNUMBER# (# TRACKINGNUMBER # is a variable which is replaced with the actual tracking number) It is highly recommended that you update the URL in your tracking emails if you are using our Custom Carrier Trackers extension, otherwise customers may be confused if a 404 page not found is displayed when trying to track their shipment. Not yet using our Custom Carrier Trackers extension? You can easily set up custom tracking links in Magento using it. The tracking numbers will automatically be replaced in the https://www.trackcourierstatus.com/track-royal-mail  so your customers don't have to manually enter the tracking number. If you are using custom carriers which are not supported by Magento immediately, you can use them to easily add custom tracking https://www.trackcourierstatus.com/track-royal-mail  to Magento.
