We build our solutions having security and performance in mind. Once you deploy the application, you will need to take care of ensuring the security of the deployment (updating the solution and its components, correct permissions, ...). In this case, do you have any backup you can use to restore the solution to a previous state? If not, I suggest you ask in the official forums of the application to get more information about what's happening and how to solve that.
Do not hesitate to write us back if you have any questions about the solution, its security or the configuration.
