"Terms of Service" registration problem

If you have issues on your registration page with DJ-Classifieds with such error: 

Warning Field required: Terms of Service

Go to: Extensions -> Plugins, search for User - Profile plugin and click to edit it

Once editing the plugin makes the "Terms of Service" setting to "Disabled"

and Save the plugin.

(It's needed as the DJ-Classifieds registration uses the same core Joomla! registration mechanism which is checking if the required fields set in this plugin are present).

In addition, it is required to unpublish the 'User - Terms and Conditions' plugin in the Joomla backend. It blocks the registration and settings from the "User - Profile" by default, although they are correctly configured will not work.
