Can you provide me a site details?

No problem.

In the next release I fix this issue.

However, I recommend the same to create a User Profile or Edit Profile menu item , otherwise the URL will become component/users/profile?layout=edit. Not fancy and not good for SEO.

I have the same problem, and solution doesen't work for me either.

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

Hi,
sorry your credentials not work, we get "Username and password do not match or you do not have an account yet."

Anyway,
Problem 1 - "Users can't edit profile. The email address entered is already in use or invalid. "

Problem 2 - "Please Enter a Name"
Easy Profile remove Name and replace it with firstname and lastname; Name fiel (required by Joomla) become a hidden field into default fieldgroup, so this fieldgroup must be enable in registration and edit profile, you can move all fields from your "Profile" fieldgroup to our core fieldgroup ("Details", after this you can change the label from detail to profile.

See screenshot: our Details (default) is a core fieldgroup.

Thanks for taking time to look at my issue.
My apologies, I had neglected to enable the user it should now work.
For problem 1, I have created a 'Registration' menu item (under our SEF menu) as I did not have one, because its usually not needed.
And I set the group to 'Guest' as suggested. I am still having the error.
Your assistance is appreciated!

As for problem 2, I see my error and have fixed it. For some reason, the 'default' tab had been changed to '0' for a core item.

Well, it would appear that I had messed up the database while trying to clean it up. I have reset your core fields with their field names, now everything works as expected!
