This is quite a neat plugin for uploading a user pic. But there are a couple of warnings that may disturb something in your site! One of these warnings is:
Notice: has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in /xyz/wp-includes/functions.php on line 2712
The solution is to use
current_user_can() instead. For example:
$current_user->has_cap('edit_users') is deprecated
You can directly change the plugin file, but it is not recommended as a plugin update might overwrite your changes (if the authors don't implement this!)
AUTHORS, please change this! ;)
Hope this helps!
