Today I opened an existing .xpj file and added two topics. I saved all changes. However, once I published the .xpj using WebHelp_Pro (Primary Layout) the HTML file and viewer does not display the new topics. Also, although i have edited the .xpj file, and was able to save all, the date of last update is displaying when it was originally created (not the current date that it was edited).
You’re using the “Pro” output because you’re publishing to a RH Server instance, right? If not, don’t use the “Pro” flavours; if you are, did you clear all the output files off the web server to ensure that what you generated was what you published? Any source control at play here? Did you need to add the topics to your ToC to see them?
