I have VM 2.0.7c and the "Notify me" link is correct only when i disable VM SEO setting (from Virtuemart/Configuration/).
When VM SEO is enabled, then the "Notify me" link directs to "http://www.my_domain.gr/e-shop/loise-detail/notify
" which does not resolve well and is then redirected to "http:// www my_domain gr/index.php?option=com_virtuemart"
The correct url for the notify page is "http://www.my_domain.gr/e-shop/rings/loise-detail?layout=notify
I believe that the bug is in the file "components/com_virtuemart/router.php" and it has been introduced after the the 2.0.6 release.
I say that because when i substitute the file "components/com_virtuemart/router.php" with the respective file from version 2.0.6 then this problem is solved.
I hope this hint will help solve the problem
