Yes, you’ll need to restart Apache for the change to take effect.
Hope that works for you.I must be doing something dumb here; I still can’t get it to work. I tried each of the two techniques again, and I stopped and restarted the server (presumably this includes Apache?) for each of the two methods. Unfortunately the non-www version still doesn’t redirect to the www version.
Carpathia is my host — does anyone here use them, and has anyone been successful at setting up this .htaccess trick? Whatever I’m doing wrong is probably very simple and obvious; I just wish I knew what it was! :blush:
