 * Hi Nicola,
    When activating the plugin, I gen an error message
 * Notice: register_rest_route werd verkeerd aangeroepen. REST API-routes moeten
   worden geregistreerd voor de actie rest_api_init. Lees Foutopsporing in WordPress
   voor meer informatie. (Dit bericht is toegevoegd in versie 5.1.0.) in /home/stichbg99/
   domains/mensenbieb.nl/public_html/website/wp-includes/functions.php on line 4773
 * And this conflicts with another plugin.
 * Can you help?
 * Mvg, Marjet

 * Hi Nikola,
 * thank you.
 * Yes I can activate & use the plugin.
    But when I activate the plugin, I get the
   error message. & then I can not use another plugin anymore. When I deactivate
   the other plugin, I still get the error message so I think it is not the other
   plugin that causes the issue.
 * Best regards,
    Marjet
 * PS no problem when you need login for the site.
