Patch SUPEE-6788 (and Magento 22.214.171.124), released on Oct 27th 2015 by Magento, introduces some changes in the Magento core that break many third party extensions.
If you are using any of our extensions that were released starting from January 2015, there should be no issues, except for the two extensions mentioned below. If you are using module versions from before 2015, you will need to update your extensions.
So far we are only aware of two extensions requiring updates:
- Magento Order Export Module: Version 1.8.7, released on Oct 28th 2015, establishes compatibility with SUPEE-6788. [However the issue caused by SUPEE-6788 only appeared if you tried to export downloadable products]
- Enhanced Order Grid: Version 1.7.4, released on Nov 5th 2015, establishes compatibility with SUPEE-6788.
Please go to "My Downloads" on xtento.com to get the latest version or renew your support and update period to get access to the latest version.
Also, cron.php cannot be called via wget anymore, and thus you will need to update your cronjob as explained in the wiki in our Magento Cronjob article.
