I'm having the same problem this guy had back in 2014: http://forum.virtuemart.net/index.php?topic=123260.msg420673#msg420673
There was no solution posted.
The odd things is that this only happens on some of my product pages, but not others.
- It happens here: http://shopbevara.com/2016-02-09-00-55-19/all-house-home-item/women-s-brands/coffee-tea/vintage-sellers/personal-coffee-pot-detail
- It does not happen here: http://shopbevara.com/2016-02-09-00-55-19/all-house-home-item/bath/vintage-check-towels-navy-detail
If you look at the crumbs in the first product page, you'll see that it appears to duplicate itself, while the second page appears to be normal.
Any ideas or suggestions?
Joomla 3.4.8
Virtuemart 3.0.13.4 (an interim version from Max)
I may be onto a fix, but I'm not sure exactly what is happening. I think it has something to do with trashed menu items.
But beware, after deleting the trashed menu items my site crashed hard. So please backup first.
