I have a WordPress site which syndicates content from a number of sources and auto creates categories and tags.
I have converted a large number of categories to tags which now leaves a ton of categories showing 404's. I started manually redirecting these but as expected this is a huge task.
I'm trying to find a way to use htaccess redirects, which can
- detect all category 404s
- redirect those to their /tag/tagterm/ equavalent
so all 404'ing /category/catterm to be redirected to /tag/tagterm equavalent
