Hi @mycraze – It sounds as something is failing to load the jquery-cookie script. BP attempts to do it in the function bp_core_register_common_scripts(): https://buddypress.trac.wordpress.org/browser/tags/2.9.2/src/bp-core/bp-core-cssjs.php?marks=54#L18
The first thing to check is to see whether the page is attempting to load the script in the first place. View the source of the page, and look for a tag that looks something like this, in the document head:
<script type='text/javascript' src='http://example.com/plugins/buddypress/src/bp-core/js/vendor/jquery-cookie.js?ver=2.9.2'></script>
If you *do* see this, but are still having the problem, try the following:
* Load the script URL directly in a new tab. Does it load?
* Open the Network tab of your browser’s developer tools. Is the browser unable to access the file for some reason? Perhaps a 404 or some other error?
If you do *not* see the script tag, then it’s a server-side issue. My guess, in this case, is that you are using a third-party theme that loads the bp-legacy JS file without also properly declaring the dependencies. To verify, switch to a default WP theme (like Twenty Sixteen) to see if the problem clears itself up. If this is the problem, you may want to talk to your theme author, or share the relevant code from the theme (probably looks like wp_enqueue_script...) and we may be able to help you correct it. In the meantime, you may be able to work around this problem by manually enqueing the cookie script in your functions.php file. Something like:
add_action( 'wp_enqueue_scripts', function() {
wp_enqueue_script( 'bp-jquery-cookie', buddypress()->plugin_url . 'bp-core/js/vendor/jquery-cookie.min.js', array( 'jquery' ) );
} );
