I don`t know what exaclty went wrong - I only know that I can not Access the Admin Control Pannel anymore nor the Forum.

This makes me fear from the future - right now I am in the testing Phase, once live this would be a no go.

Does anybody know how to fix this?
Is this normal, that the whole board can go down that easy?

now everything is normal again :whistle:

But anyway - if also other members are reporting to have Problems like this, maybe there should be displayed a message that the board is currently down.
Isn`t it a security whole, if the user gets this Error trace I posted :eek:

With this message, he knows the root path (H:/root/home/xxx/www/yyy/index.php).

Please tell me if it is technical not possible to supress such Output and just Show the page with a customized Error message.

I would say so. That's a full path disclosure and if the error displays for everyone, it's a problem IMO. I assumed it would only display for admins, but if even guests can see it, there's a problem.

Back traces are only shown in debug mode or to admins in the control panel. Debug mode should never be enabled in production.
