Updated the engine to be compatible with the recently released CS-Cart v.4.7.1 editions. Some CS-Cart admins reported that the add-on not listed properly the unique canonical URLs on the CS-Cart admin panel if the id for product, category or content page was the same. With this version this issue has been fixed.
Also there are some other code optimizations to improve the speed, stability and security.
Update is highly recommended. You can download the latest version from your account. Un-install the previous version and install the latest one.
