We have upgraded virtuemart to 2.0.22b. Joomla version is 2.5.14. Now after browsing page breadcrumbs are correct. But after browsing any category if we search any other item from other category, it is showing incorrect breadcrumbs.
How to solve incorrect breadcrumb issue after searching item?
First I suggest you update to VM2.0.22e - http://virtuemart.net/news/list-all-news/446-important-security-release-vm-team-at-joomladay-germany
There could be an issue with your menu links to VM affecting the breadcrumb path - I have never experienced this problem, though.
Do you have menu item for VM Front Page?
