Vesta Control Panel - Forum

I use VestaCP for my vps. I created three websites, they're fine. Today, I login VestaCP by admin's account, then, I changed Password and Email and Language (Vietnam - vi). I logout, then I login again, but, 505 Internal Vesta Error appear. I can't login to VestaCP. http://www.upsieutoc.com/image/Wu...
