Today, X-Cart 5.2.20 Hot Fix has been released. The main purpose of the release is fixing license keys verification error which results in the inability to use features activated with the license keys.
Besides, the release includes a couple of other updates: we changed the URL for Australia Post API as the old one will be suspended soon; and fixed the review rating issue – a wrong rating was displayed in the review editing popup window in the admin area.
Upgrade to the new version is already available in all live stores running on X-Cart 5.2.x. The issues don’t affect X-Cart 5.3.x.
