I activated WooCommerce 1.4.2 plugin and now my site is completely down. This is not good. I previously had activated Jigoshop but deactivated and removed it. I reinstalled WooCommerce plugin in case of a conflict. I've contacted the creator of the WP theme (Mayashop) and they say their code is fine--that it is WooCommerce plugin. So how do I regain control of my site?
Fatal error: Call to undefined function is_main_query() in /home/mkbrewer/public_html/wp-content/plugins/woocommerce/classes/class-wc-query.php on line 32
