Hello,
The problem with pathway is again caused by VM itself not counting with SEF urls. This time, the fix needs to be done in VM.
File: /administrator/components/com_virtuemart/classes/mainframe.class.php
Line 363: $cmsPathway->addItem( $item->name, str_replace('&', '&', basename($item->link)) );
Remove the basename function around $item->link, so the line becomes: $cmsPathway->addItem( $item->name, str_replace('&', '&', $item->link) );
This should be probably noted in VM's own forum.
Best regards,
