Thanks everyone, I've just managed to get rid of the error. I set the display variable ":0" and then did a "xhost +". I also had to get rid of the headless parameter, as you said I didn't need it. Now my report successfully appears on my server. The thing is that I wanted it to be shown on the machine that requested it. If I'm in a client machine and request the report, I want it to appear on this client machine. But the way it is, it always appears on the server. But I think this is not a problem to be solved on this list, is it?
