Hello,
I found a possibile bug in breadcrumbs link in journals with url rewrite.
When you are in a third level place, e.g.
Home > About the Journal > Submissions
you find these link URLs:
Home → www.journal.net/index (OK)
About the Journal → www.journal.net/about (ok)
Submissions → www.journal.net/index.php/path/about/submissions (error)
The third one is to a link different from the others, because it shows the journal path and the index.php, potentially breaking the rewrite.
Here is an example
