Hello I am using Joomla 1.7 six in my site and I have replace the front banner named personal2.png. My problem is I didn't change the file name. when I use http:// only it works with my new banner But when I use http://www it does not work but loads the old banner. This is really very peculiar problem I am facing. Can anybody give me any suggestions?
It's a unique problem and I've not faced this kind of problem till now... You can change .htaccess file to use www always and replace the old banner with the new one...
You should alter the code in .htaccess file. Once you will place the right code there it will work as usual.
It seems your are possibly running two versions of your site a www and non www. Try doing a 301 redirect from your non www domain to your www domain and see if that solves the problem. (may have to do it the other way).
Solution: Force users to use the WWW or Non-WWW version of your domain Check detail here to use .htacess joomquery.com/en/seo-sef-sem/64-seo-sef-sem/1221-force-users-to-use-the-www-or-non-www-version-of-your-domain.html
