avatars wont load from frontend!

Hello, how to make simple local avatars working with WP User Frontend? I tried to replace in wpuf-editprofile.php line:

<?php do_action( ‘show_user_profile’, $profileuser ); ?>

to:

<div id=”userProfile_container”>
<div id=”userProfile_avatar”>
<?php echo get_avatar( $userdata->ID, 90 );?>
</div>
<div id=”userProfile_controls”>
<span>Update your avatar (.jpg, .png, .gif)</span>

<input type=”hidden” id=”_simple_local_avatar_nonce” name=”_simple_local_avatar_nonce” value=”263d2a8f8d” />
<input type=”file” name=”simple-local-avatar” id=”simple-local-avatar” />

</div>
</div>
But there is no result, after upload avatar is set to default one. Anyone can help?
