[Solved] User can't change his email address
In the new release, 1.4, a user can not change his email address.
As a test user I changed the email address in the profile, there was a confirmation that it was successful but it was not changed.
The only way to change it is in WP admin.
Please update to wpForo 1.4.1 version. This was 1.4.0 bug.
