Hi folks,
on my store can access only the registrated users by myself. But,unfortunately, at first checkout the users can modify username and password.
In order to remove the section at the bottom of the checkout page where it allows you to pick a username and password, I inserted on \skin1\customer\main\register.tpl this condition :
{if $usertype ne "C"}
{include file="main/register_account.tpl" userinfo=$userinfo} {/if}.
So, this modification is OK, but when the user needs to modify the others fields as shipping address, or others allowed fields, on to Profile details, he receive this error message

Access denied !
You are not allowed to access that resource!
Error ID: 36

I'm looking for way to allow to users to modify only limitated information on Profile.
Thanks for your support.
Bye
