@SarahBo2Check body.noloudconfig.html first for possible concern if not then traverse base to parent sighlty/htl scripts to debug.
Default xfpage page location:/libs/cq/experience-fragments/components/xfpage/, once you were able find the relevant script do overlay and let sling resource merger do the magic.
If you need more assistance you have to post your code to further debug.
