Events Manager – Forms Editor not working / showing up

Hi,

I am using Events Manager as the administrator of my website. For the first time, I need more information of my users than just their email address and name.

So I was trying to find the forms editor but it doesn’t show up anywhere…
Since it didn’t show up, I tried using the direct URL (http://www.*****.be/site/wp-admin/edit.php?post_type=event&page=events-manager-forms-editor) but it tells me that I don’t have access to this page.

I already checked user permissions and every single box is ticked for administrators…

Thanks in advance!
