Kinda late but I just ran into the same problem
open up aleph-user-tags.php
and change the function on line 177 to read
function aleph_the_user_profile_link($caption = '', $authordata = '') {
if($authordata == '') global $user;
else $user = $authordata;
$profile_url = aleph_get_user_profile_url($user);
if ($profile_url !== false) {
if (empty($caption))
$caption = $user->display_name;
echo '<a href="' . $profile_url . '">' . $caption . '</a>';
}
}
This should solve your problem
