Hi ejikas!
I have the same problem. I need to use the same custom taxonomy slug than my custom post type slug.
I have a custom post type with slug “press”, and the post permalinks have this structure:
mysite.com/press/postname
In other hand I have a custom taxonomy with id “presscat”, and I need it to have the same slug “press”. This taxonomy has terms like “news”, “case studies” and “factsheet”, and I need a permalink structure like:
mysite.com/press/news
mysite.com/press/case-studies
mysite.com/press/factsheet
The problem is that if use the same slug for both cases, I get my custom posts (with url “mysite.com/press/postname”) as if they were terms of the “press” taxonomy (“postname” as term). I tried to fix it with the “template_redirect” hack, but like ejikas, I get the same 404 error.
Anyone has fixed this issue?
Thanks!
