Hi,
please post me your site details. you can use the form below the reply in "Site Details" tab

Hi,
we have found the problem.

Registration/edit profile pages are the same of Joomla, Easy Profile customize these form by "Easy Profile - Users plugin".
This plugin was set with "Special" Access Level so works only when administrator do a login, now I have set this on "Public"

Oh my.... Such a simple solution - and yet so hard to find out! Thanks a lot!

Oooh...I'm sorry, but the problem is still there. Now, when I try to register as a normal user I find the core fields and two EP fields. Many more fields should be viewed. Is there a limit to how many fields may be viewed?

Hi,
this because you have set for many field "Special" on "Availability for" parameter, so these field are available only for administrators. Set on "Public".

When user try to register an account their privileges are "guest", With "Public" the fields are available for all members (Guest, Registered, Administrator,etc...)

Aaaah..... all these settings are confusing. I hope I'll get there in the end. Tanks again!
