We recently upgraded to RoboHelp 2019 and have noticed that the xmlreadhelper.js file is missing when we publish our Help projects using the WebHelp output. This was causing some issues in the Help build process. As a short term fix, it was manually added from an old publication that was completed in our previous RoboHelp version, and the issue seems to have been mitigated. After some cursory research, I can't seem to pinpoint the function of this file and why it seems to have been removed from WebHelp outputs.
Any information the community has on this would be great.
