The solution for J3 was to alter the settings in Breadcrumbs to set "Last" to Hide in the Breadcrumbs module. However in J4 this has a stange effect - illustrated by the two images below:
The Solution
In summary - you have three options as follows:
- Use the default and have Google make comments
- Use the J3 solution and have an erroneous Breadcrumb
- Dump Joomla's Breadcrumbs in favour of that from www.uwix.nl
The procedure is as follows:
- Install BreadCrumbs Advanced Module - https://uwix.nl/downloads-edoc-mnu/bca-edoc-mnu/breadcrumbs-adv-edoc-340/download.html
- Set module breadcrumbs position to none, and unpublish. [save overhead]
- Set module breadcrumbs advanced position to breadcrumbs, and publish. Do NOT forget to enable menu on all pages !
- Disable breadcrumbs. [save overhead] - NOTE: The extension "mod_breadcrumbs" (ID 204) is locked and cannot be uninstalled.
