problem with link 'Edit profile'


wpmspp is a multisite.
My problem is on one multisite :

I defined a membership zone, all is OK.
But on public site, after connection, i go to my profile page.

But if i click on edit button, the page reload but nothing. The fields are not editable !

The action parameter is in the url.

I don't have any errors in Javascript or PHP.

What is the problem please ?

Thanks for your help,
