RoboHelp 2019 The HTML tag "?xml version="1.0" encoding="utf-8"?" is not a valid HTML tag
I am getting this error on several topics in my project: The HTML tag "?xml version="1.0" encoding="utf-8"?" is not a valid HTML tag (it does not begin with an alphanumeric character).
I am using RoboHelp 2019 (Classic). I go to Output (SSL) and right-click on Miccosoft HTML Help (Primary Output) and choose Generate.
This is not a new project. I've generated .chm files from this project before. Looking in RoboHelp, the project folders are "empty", however, going to Windows Explorer the files are there.
Is there any fix for this error?
For reference, this is the HTML code at the top of one of the topics:
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
