 * Hi Axel,
 * Do you have any other security plugins installed and activated? We’ve seen conflicts
   with this feature caused by other plugin.
 * Thanks,
    Brian

 * Hi Axel,
 * The next most likely cause is the theme — some theme authors have their themes
   display pages before WordPress normally would, which causes query strings to 
   be lost. (The part of the URL after the question mark.)
 * If you can temporarily switch to one of the default themes like “twentyfifteen”
   and try the link again, that would confirm if the theme is the issue. Most theme
   authors seem to fix it in their next updates, if they know about the issue.

 * Hi Matt,
    since its my businesswebsite and we had an issue with CPTs a while 
   ago i do not dare to switch the theme. You know …. Murphys law
 * Is there another way to find out if its the theme which causes the trouble?

 * Hi Axel,
 * Yes, that is understandable. I don’t know of any other good way to test if the
   theme is the issue though, unless you have a second site where you can try installing
   the same theme.
 * It is almost always caused by the theme though, so you could try asking the theme
   author if they are responsive to support inquiries. I believe the WordPress hook
   that usually causes the issue is template_redirect — if the theme uses it to 
   load its templates, that’s usually the issue. (It’s meant for redirecting before
   loading a template, but its name may be confusing.)
