Indeed, I used the Cpanle's File Manager to edit the config.php file, and this editor seems to always insert a new line after after the final ?>. I tried a different editor and this solved all problems from my previous post, including the display of uploaded htm files.
Jan, thank you for responding. Before I posted my inquery, I briefly searched the forums. I found so many posts that I could not notice a relevant answer. Next time will be more careful. Thanks again.
