RESOLVED 10 November 2015 10:45am - This issue has been resolved. A connection to the image database needed to be re-created after deployment of an update. Thank you for your patience!
We are currently investigating an issue with the Image Manager in the Drag and Drop and Freestyle email template editors. Users whose accounts are hosted in the EU data center may encounter issues trying to access or upload images. This is being treated with the highest priority. Updates will be posted here as they become available. Thank you for your understanding.
