I just installed a fresh Joomla 1.53 eCommerce Edition on a hosting company.
You must have Joomla 1.53 eCommerce Edition or the Joomla 1.5.3 and VirtueMart 1.1 separatelly.
step 1 - Download what you need:
-Artio JoomSEF 3.02http://www.artio.net/en/downloads/joomla-extensions/artio-joomsef-3-0-0/download
-VirtueMart 1.1 plugin for Artio JoomSEFhttp://forum.virtuemart.net/index.php?action=dlattach;topic=39744.0;attach=6668
step 2 - install artio JoomSEF and carefull with that...
!!!!! Artio JoomSEF automaticaly generates .htaccess file so you must delete htaccess.txt file.
Step 3 - Joomla Configuration - some things you must do
Search Engine Friendly URLs - YES
Use Apache mod_rewrite - YES
Add suffix to URLs - NO
Step 4 - Install the Artio JoomSEF for VirtueMart 1.1 in the Artio JoomSEF control Panel.
Step 5 - Configure Artio JoomSEF
-remove itemID's, show full titles and so on
I am still testing and waiting for other user opinions and feedback on this configuration!
A localhost instalation with the configuration described here does not work! You must use a webhosting service, and not just everything, learn about Joomla installation requirements.
So far I have found that when I click the empty cart, it opens a new tab/window with www.virtuemart.net
so I don't like that. Checkout, product browsing and searching and Xmap work OK.
Hope this was helpfull
