BuddyPress Profile Pics - Unable to Crop

I am able to upload my members' profile pics and crop them appropriately from admin, but my members are unable to crop their own uploaded pics. The crop button is there but there is no way to manipulate the image so you just get a chunk of the picture.

I have done a lot of research on this issue and it seems to be a very common problem with reasons such as:
1. this was solved when there was an additional js file being called from the footer in the Reverie file:
<script src="<?php echo get_template_directory_uri(); ?>/js/jquery.min.js"></script>

2. My solution, which I found some where else in this forum: I put the following two lines in /wp-content/plugins/bp-custom.php:
define( ‘BP_AVATAR_URL’, ‘http://’ . $_SERVER . ‘/wp-content/uploads’ );
define( ‘BP_AVATAR_UPLOAD_PATH’, $_SERVER . ‘/wp-content/uploads’ );

3. remove <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> from header.php

4. add the following to bp_custom.php
// Javascript conflict
function mytheme_enqueue_scripts() {
wp_deregister_script('jquery':wink:;
wp_register_script('jquery', ("http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js":wink:, false, '1.4.2':wink:;
wp_enqueue_script('jquery':wink:;
}
add_action('wp_enqueue_scripts', 'mytheme_enqueue_scripts':wink:;

Needless to say I have tried several of these and none of them have worked for me.

Could I ask you to help me resolve this problem please.
Attached is a screenshot of what my members see when they upload a pic and are unable to crop it.
