what's you mean mysql database data?. Other mysql data still exists.
First of all, thank you for your reply, I have asked the service providers to provide backup, but still need to give you a friendly advice. Kloxomr need to develop better, when you update the program need to be more rigorous so as to avoid causing too many problems?You were writing help documentation needed to avoid the user to perform the wrong operation.
Also, you need a sound different versions of kloxo-mr, not force users to upgrade to the latest version. Maybe you need more people to join your team, so as to have a better development.
