I was just alerted by Google that my site is producing a 404 page (due to the fact that I recently removed a category that once was there--see screenshot).
Is there any way to set up a redirect so I can redirect this old page to the new relevant one?
There are a lot of Opencart extensions that enable redirects. Or a quick google search will point you in the direction of creating one in your HTACCESS file if you are confident with code.
