Easy Profile - Joomla Extension

I just noticed that my front end was not saving Edit Profile changes. I have always had a Menu item for Easy Profile and an Edit Easy Profile. I could always save changes on back-end User Manager, and on front end Edit Profile (except when edit profile did not work because of the rokinject plugin problem already solved). Previously I had this problem and we had to turn off rokinject plugin. The the save Edit Profile changes worked again.

I use a form program to "register" new users. So there is no "regisration" menu. I have always only had the Profile and the Edit Profile Menu items in the Main Menu.

Note, I can still go to the backend User Manager, edit a User, make a change, and the changes will save in the back-end (and will then show up on the front-end). So my only problem is saving front-end changes using Edit Profile menu item.

***************

Problem - If I go to front-end Profile, then Edit Profile (using the button Edit Profile or my menu item Edit Profile, make any change and hit "submit", then I get this warning.

"Warning The username you entered is not available. Please pick another username. The email address you entered is already in use or invalid. Please enter another email address.

I want to keep username and email as is. But I tried to change username and email anyway using front-end Edit Profile, and these two changes did not save and I still get the same warning.

There are several other forum posts that say if you have a registration menu item, it should be set to "guest" and that the Profile and Edit Profile Menu items should exist too.

Although I do not have a registration menu item on the site, I set one up anyway with access set to guest to see if I could then go to Edit Profile to save changes to profile. But the problem still persists when saving a front-end change under Edit Profile. So I deleted the registration menu item, and I am back to just the Easy Profile and Edit Profile menu items.)

I also turned off the Global Config > SEFriendly, but the warning still occurs when saving a front-end change under Edit Profile.

Is there maybe a problem with the alias fields not matching the easy profile fields? Maybe that is why the Edit Profile is not saving?

(One of the above support posts stated that there was an alias problem, and the jsn_users table was rebuilt to match the fileds with the alias fields. But I am not sure if that is a problem here.)
