Redirect issue

Hello,

I am having an issue when I try to log in with Twitter and Google+

It works but ever I authorized

it gives this error.

Warning: Missing argument 2 for woocommerce_load_persistent_cart() in /home/store/public_html/wp-content/plugins/woocommerce/woocommerce-core-functions.php on line 215

Warning: Cannot modify header information – headers already sent by (output started at /home/store/public_html/wp-content/plugins/woocommerce/woocommerce-core-functions.php:215) in /home/store/public_html/wp-content/plugins/nextend-google-connect/nextend-google-connect.php on line 175

After I get this error, if I load the website it worked. I need to fix this error.

Thank you,
Tyler S
