Hey Martin,
I’m sorry to hear you’re running into an issue on your WordPress website.
Are you sure this is with our plugin? Because our plugin has a screen that asks for the amount of related posts you like to link before linking. On this screen you also have to click “Link now” before it does anything. Also in one of the email you sent me there’s a screenshot of a different related posts plugin.
It is true that in our plugin, on (re)linking of related posts all existing related posts are replaced with what the plugin finds more related at this point in time.
In any case (if you use this plugin or a different one), to restore a previous database state, you will have to revert to a backup of your database. If you do not backup your database yourself, there’s a high chance your host does this for you. Please contact them to see if they can assist you further in this matter.
For the sake of communicating via one channel, please reply to this topic and not via email. Thank you.
Kind regards,
Barry
