Jerett I can confirm I am having the same problem as you, have you been able to fix it yet? Mine are both stock unmodified and I am getting the same exact error.
I am using VPS/Dedicated server right now and my module is using the hostname for the username, is there anyway to automatically add ".vm" to the end of that for every customer when they sign up? Therefore, for example if they entered for the hostname "something", I want it to automatically save as "something.vm" is that possible? IF it is can someone help me with that?
Thank You
