As of now i'm using this code to echo user's profile url.
<?php echo esc_url( home_url( '/' ) ); ?>user/<?php echo $current_user->user_login ?>"><?php echo $current_user->user_login ?></a>
This link uses author base as "user". So when i change author base this link will be broken.
IS there any function available like current_user_profile_link() ?
