Another question regarding the button "edit the profile" from the front-office interface of the site. when i click on the button edit after having to identify of course. the link redirects me to the home page without giving me the opportunity to edit my profile ?
Probably this happen because you does not have any menu item of type "Users->Edit Profile". Without this menu item edit profile page inherit home page menu item id.
Try to create a menu item of type "Users->Edit Profile". If this not solve your issue then please send me your site details to check this (you can use the form below the reply in "Site Details" tab)
