I have defined a tag "bookblogger". All threads tagged with "bookblogger" are visible at /tags/bookblogger. Let's say I have a thread "test" with id 253 tagged with "bookblogger". The title of the content snippet on the bookblogger tag page links to /threads/test.253, which is fine. However, every snippet also has a link to the corresponding forum, in this case /forums/cafe. This also works fine in general, but only for forums where you don't have defined a Route Filter. In my case a route filter is in action. /forums/cafe is routed to /mynewname/cafe . When you now click on the forum link within the bookblogger tag page you are still routed to /forums/cafe leading to a 404. It seems as if route filters are not considered on tag pages under some circumstances. Any ideas what I can do?
