Recently I changed my blog from the standard /%year%/%monthnum%/%day%/%postname%/ to /%postname%/
However the blog is 5 years old and I'd be able to not get 404 errors on "old" links. don't really want to overload the site with plugins, henc eI thought it would be easy to add a rewrite rule in .htaccess
However I am somewhat stuck and would appreciate some help.
I thought that a simple
RewriteRule /([0-9][0-9][0-9][0-9])$/([0-9][0-9])$/([0-9][0-9])$/(.*)/ /$4/ [R]
Would do the trick, but it doesn't. Can anyone point me the right way? thanks
