Fatal Error Call to a member function get_cart_contents()

[ogiebobogh]

I recently upgraded to v1.5 and now many pages in the site dashboard aren't loading and I'm seeing the following PHP fatal error.

`[26-May-2018 15:02:43 UTC] PHP Fatal error: Uncaught Error: Call to a member function get_cart_contents() on null in /home/public_html/oslhatestsite/wp-content/plugins/pmpro-woocommerce/pmpro-woocommerce.php:126 Stack trace:

I'm seeing many similar errors. @eighty20results can you look into this?

I think this condition may not be working correctly: // only change price if this is on the front end if ( ! is_admin() || defined( 'DOING_AJAX' ) ) {

Here is another one that show it is firing on the admin. I think that condition needs to be changed to an && as well as maybe ! defined ('DOING_AJAX')
