Urgent help needed. Issue after cwp update

Hello !

My name’s Alex ANIHOUVI.
We are using CWP Pro for management of our WebHosting Service.

But since hours now, our clients are experiencing really anoying issue on their client area. When connected to cwp's user panel, nothing is working. No button is working, no service is working. All off them lead to a blank page. For some buttons, nothing happens when we click on them.

Please help us resolve this issue very urgently.
Is it possible to reverse back to older version of CWP please ? If yes, how can I procced please ?

Thanks a lot

I guess it's too late, but manually CWP update must fix the problem.
