This issue is resolve,
Solution: If you have Auto User register plugin ” Easy Digital Downloads – Auto Register ” the these setting cannot be saved.
In order to save those setting, please disable / Deactivate the plugin.
Thanx, Im already using that now it has both the features. without taking users to login panel.
Using with Ultimate Users + Frontend post submission
Actually I missed to copy the php and css files in my theme after copying those files, I can see the dashboard of submitted posts.
But users are unable to edit their own posts if they want? Is there any feature they can edit the post again ?
