Error after migrating website

I have this error showing up on my header:

Warning: array_filter() expects parameter 1 to be array, boolean given in /home/englishaffair/public_html/wp-content/plugins/woocommerce/includes/class-wc-cart.php on line 212

I suspect it might because I had an item added to cart before I backuped up the site and migrated it to another domain. Or it could just be nonsense, and the error is something else.

This is really annoying. See here.
