Warning: array_shift() expects parameter 1 to be array, boolean given in….

I was in the process of duplicating my website and decided to reduce the size of my file so it would be easier to duplicate. I accidentally deleted the Woocommerce plug-in which came as default with the them I purchased and quickly reinstalled and activated it. But now I am getting two errors when going to my website.

1) Warning: array_shift() expects parameter 1 to be array, boolean given in /home/numeraldesign/public_html/highflyersolutions.com/wp-content/themes/medicure/header.php on line 147

2) Warning: array_shift() expects parameter 1 to be array, boolean given in /home/numeraldesign/public_html/highflyersolutions.com/wp-content/themes/medicure/header.php on line 264

Website address is: highflyersolutions.com
