I am aware of the fact that Xdebug is incompatible with Ioncube (that encodes the PHP-source code).
We use DaDaBIK (https://dadabik.com/) that uses Ioncube for its own PHP-code.
But one can add custom PHP-code for implementing certain special functions. I did that quite succesfully but with much effort to debug my own code.
So it would be great if Xdebug would be able to do this debugging on the non-Ioncube-encoded PHP code.
Now, we even cannot start DaDaBIK when Xdebug is active - we get the error "503 - Service Unavailable".

Is there anything you can do about this?
