Make "Internal errors" more verbose and show a modal-dialog pointing out what's wrong #627
Description
Is your feature request related to a problem? Please describe.
There are often issues trying to create certificates f.e. which sometimes results into a javascript-alert simply showing "Internal Error" without pointing out what's the reason for it.
Describe the solution you'd like
A modal-dialog and more verbose error-handling that show a more detailed reason what is going wrong. In simplest case a modal dialog showing the original error that is "behind" the Internal error message (even if it may be more technical at all - it's better than absolutely no clue what's wrong).
