Please follow the below method if you want to edit the Default Dashboard Menu ( Profile Page )
In our LMS theme , by default we have user profile page with their course purchase details.
In that page user can view their subscribed courses, current status for the course, assignment and quiz statuses and user can edit their profile page also.
Open the file in this path wp-content/themes/lms/framework/loops/content-userdashboard.php using some editor like DreamWeaver and scroll to line no: 36 approximately.
There we have added the code for “Welcome page menu” you can edit the menu as per your need.
Login to your Admin Panel and navigate to Pages > Add New. After that you have to assign ” Welcome page Template ” then only when user click their name it will display the profile page.
Note : When you have not assign the welcome page,it does not display the profile page,simply it will reload the home page.
