There is no pagination on the user's question/answer list.
I see that in /user-question.php/ the query is using posts_per_page of 20, but there is no pagination automatically appended to the bottom of the list (i'm not sure if this setting is supposed to automatically do that or not). Also, there is no call in the HTML lower down in the file for any type of pagination.
Please see the attached screenshot as a point of reference.
Any recommendations for adding it? I'm editing my template files, but this may also be a bug that might need fixing in an update.
