I receive the following messages when I try to log into the back-end of my website:
Warning: Missing argument 2 for woocommerce_load_persistent_cart() in /home/electpas/public_html/wp-content/plugins/woocommerce/woocommerce-core-functions.php on line 175

I receive the following message when I try to view my website:
Fatal error: Call to undefined method WP_Query::is_main_query() in /home/electpas/public_html/wp-content/plugins/woocommerce/classes/class-wc-query.php on line 34
HELP! HOW CAN I FIX THIS!
Try the usual fixes: Upgrade/reupload Woocommerce, update Woo Themes framework update the Woo Theme itself.
It won’t even allow me to log in the back end to make changes. When I type my log in and password I only see a white screen with that black text.
I have only ever seen this error after moving WordPress from a DEV to a permanent location. It occurs because of an issue with the Janrain Engage plugin, post move.
Check your plugins, one of them is causing the issue.
I’m have the same trouble installig woocommerce, my website now only shows:
Fatal error: Call to undefined method WP_Query::is_main_query() in /homepages/44/d383697281/htdocs/app383697293/wp-content/plugins/woocommerce/classes/class-wc-query.php on line 54
I’ve already tried all the other plugins and reuploaded the woocommerce plugin. Anyone any idea what might be the cause and how I could solve it?
Btw when I click on the Woocommerce configuracion button in the WPmenu, I get this message:
Fatal error: Call to undefined method stdClass::add_help_tab() in /homepages/44/d383697281/htdocs/app383697293/wp-content/plugins/woocommerce/admin/woocommerce-admin-content.php on line 23
Does anyone have a solution for this error? I am trying to install WooCommerce without any luck.
I have created a fresh install of WordPress locally on my dev machine, have deactivated all plugins except WooCommerce so there should be no conflicts, have re-installed the plugin numerous times, have made sure everything is up to date, and am using the WooTheme MyStile. I can get into sections of the Admin site but whenever I try to view the front end I get:
Fatal error: Call to undefined method WP_Query::is_main_query() in C:\…\wp-content\plugins\woocommerce\classes\class-wc-query.php on line 54
System Status is as follows:
WooCommerce version 1.6.6
WordPress version WP 3.2.1
WooCommerce by WooThemes version 1.6.6
PHP Version 5.2.9-2
Server Software Apache/2.2.11 (Win32) PHP/5.2.9-2

Thanks, I would really appreciate the help.
