I’ve hade problems with the Joomla! breadcrumbs module being cached, so the wrong breadcrumb is being displayed. The problem is that the module is being cached. This has been reported as a bug and it has the status as being fixed. However, in an old Joomla! install, which is updated to the latest version, I still had this problem.
This is how I solved it.
- In the breadcrumbs module, under the Advanced tab, set Caching to No caching and Cache Time to 0
- In the Global settings, use Conservative caching (if Progressiv caching is used, I still had problems)
