A huge thanks to Colin and Arno! Once again you gentlemen have assisted me in solving a problem.
After following the above documentation, I am happy to report that my site is back to normal. Arno & Colin are the best. You two not only guided me to the outcome I wanted, as always, you both helped me learn. For that I am twice as happy and thankful.
Cheers to Colin and Arno!!!
