I did have sefpatch_virtuemart installed on my web site at www.searchwomen.co.uk but got some error when I upgraded from a previous version of Artio. Where can I download this sef patch from?

This patch is a part of the VM plug-in installation file. So if you had it unistalled in any way, just uninstall and reinstall the VM extension for JoomSEF. You can do that right away, no harm will be done.

Thanks jirka. That's fixed my problem, didn't realise it was packaged with the virtuemart extension I bought. Installed this, then my web site didn't work but quickly realised there was an upgrade available. Upgraded and now everything works fine.
