I have attempted to dowload and activate the plug in WooCommerce. I chose the auto installation and can see the plug in my list; however, when the plug in is activated I get the following error -
Fatal error: Call to undefined method WP_Query::is_main_query() in /home/content/37/7621237/html/wp-content/plugins/woocommerce/classes/class-wc-query.php on line 54
This is all that is on the page. I have been able to access my website by keeping the page open in another window and deactivating the plug in.
