I recently changed my permalink structure and I'm in a bit of a pickle. The original permalink structure was /%postname%-%post_id%/ and I wanted to change it to /%postname%/. The rule is something like this RedirectMatch301^/dir/([^/]+)-(\d+)/$ http://example.com/dir/$1 Code (markup): While the above code works, I encountered a problem where some articles that end in digits, are incorrectly redirected and the site gives an error. For example: www.example.com/best-video-converters-windows-10/. The rule cuts away the 10 bit, making the article 404. I found a workaround by using a regex limiting the number of chars and the code is: RedirectMatch301^/dir/([^/]+)-(\d+){3,}/$ http://example.com/dir/$1 Code (markup): And this code works...unless the article doesn't end in a year or something. Example: www.example.com/best-movies-2017/ Bottom line, I have no idea how to get around this and I need a bit of help
