I one of my headerfiles, I used the command \setmathfont[]{XITS Math}, once I tried to compile the document as always with xelatex, I get the following error:

! Undefined control sequence.
l.87 \setmathsfont
                  []{XITS Math}

Also, for some reason, XeLaTeX seems to hang when I comment out that line.

This may or may not be relevant:

you have a typo, you wrote \setmathfont ... but the logfile clearly shows that you typed \setmathsfont mark the extra "s".
