@Jessica Mon, Ms
I tested by creating my own page with HelpNDoc and it is rendering normally. I believe you might not have uploaded all the folders from the html folder that was outputted. Please make sure to upload these. If you are using Storage Explorer simply choose Upload and folder, then you can upload each individual folder.
Hope this helps! Let me know if you are still seeing issues after uploading these folders and I will do my best to help.
