During the process of upgrading Boru there was sadly a few accounts that did lose all files, including some crucial for cPanel to work correctly (these includes domain handling files). In fact the entire home directory was lost for those accounts that are affected. The databases are still intact and you should be able to access them through phpMyAdmin and take backups where needed, if you do have a problem with this part we can help extract database backups for you. We apologies for the inconveniences caused due to this. As a compensation we will be offering Illuminated upgrades to those affected. ADD: For clarification, you would get the first 5 years with Illuminated free, if you wish to continue after that it would come with a cost, which currently is $60 for 5 years. If you were affected by this, please open a support ticket if you haven't already done so.
