Recently i changed the theme on my virtuemart but after the change products no longer had SEF urls.

I upgraded from the default theme to yegendoo's 'vamazing'.

My site: www.brittaniafoods.ca

I would really like my site to have SEF urls throughout (and the reason I paid for this to begin with).

Any help or advice for this is very much appreciated.

Hello,

the reason for this could be that the tempalte does not follow the Joomla and VirtueMart API and does not parse the URLs through the default router, where JoomSEF is mapped.
Therefore, JoomSEF does not process the URLs and cannot make them SEO.

I am right, then to fix this, patching the template would be needed in a way that each URL is proccessed thorught the neccesary API function.
