I am using TeXstudio as an editor. When errors occur, TeXstudio does not compile the pdf at all. I know of other editors, that there is a way of ignoring the errors and still compile the pdf. Of course, it might look different than intended, because of the errors, but at least you get a pdf and know what the error actually does to your pdf.
So, I couldn't find out how to do this in TeXstudio, does anyone know?
