Front End Suscriber Event Post

Hi ! I would like the members of my site being able to post their own events from front-end :

- I installed "Capabilities" plugin and set the settings "Publish Events" + "Edit Published Events" for "Suscribers"
- I installed "Front-page editing" plugin and in settings I set the page "testevent" just created with a [eab_event_editor] in it.

I've done nothing else and it's not working :
- the page "testevent" is blank
- there's not publishing option anywhere for the suscriber even in admin panel
- if I copy the event creation link (finishing with : post-new.php?post_type=incsub_event) then Wordpress tells me I don't have the rights to access this page.

Am I missing something ?

Thank you !
