WooCommerce conflict with Memberships plugin

Hi,

I have recently taken on a client that was having some issues with her site. I say this so you know that I do not know what has been modified on the site up to this point.

We are having an issue with the products within WooCommerce being able to be displayed within a category page, but only in IE and Firefox. Chrome seems to display everything fine. The issue can be viewed at this page http://tinyurl.com/n9428rn

I have done the normal steps of disabling all plugins and using the default theme and discovered that the conflict is with Memberships plugin.

I activated the debugging mode and got these errors:
PHP Notice: wp_enqueue_script was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or init hooks. Please see Debugging in WordPress for more information. (This message was added in version 3.3.) in /home/waldorfe/public_html/wp-includes/functions.php on line 2959

Warning: session_start() [FUNCTION.SESSION-START]: Cannot send session cache limiter – headers already sent (output started at /home/waldorfe/public_html/wp-includes/functions.php:2959) in /home/waldorfe/public_html/wp-content/plugins/wpmu-dev-facebook/lib/external/facebook.php on line 49

I have contacted the developer of the Memberships plugin and am waiting for a response. I thought someone here might be able to point me in the right direction of trying to find the problem.

We are using
Wordpress 3.5.1
PHP 5.3.2
WooCommerce 2.0.12
Membership Premium 3.4.4.1

Thanks for any assistance
