I have an older site using joomla 1.0 and JoomSEF v2.2.6. I have set up a few 301 redirects, but they do not appear to be working. Is there some step i have neglected to take?

Hi, could you post a few examples of your 301 redirects?

Moved from URL - belleruthnaparstek.com/ Moved to URL - www.belleruthnaparstek.com Never
Moved from URL - belleruthnaparstek.com/index.php Moved to URL - www.belleruthnaparstek.com Never

I also tried to purge sef urls recently and that isn't working anymore. It used to work.

When i pasted the text in it removed the http:// from the urls

These URLs won't work. The 301 redirection feature can only handle the relative part of the URL, not the domain, so you will need to use custom redirection rules in your .htaccess file to redirect from non-www to www, like this:

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule (.*) www.belleruthnaparstek.com/$1 [R=301,QSA,L]

You can find more information about .htaccess redirects on Google.
