it is most likely totally wrong to ask our theme’s developer team: But is there a chance that you know of 301 redirects for posts in WordPress or GP without any third party plugin?
We use Redirect to send traffic from older permalinks to those that were changed. This works properly. Unfortunately we now have a situation where certain URLs are 301 redirected without the plugin being involved.
Why do I ask you? Since I could not find out about a WP core function, Redirect certainly has no entry on that, the data-base is clean, local and server chaches were flushed, no Yoast pro installed, we are helpless on this and I just want to sort out that it might have something to do with GP or GP premium.
