Hello, please help, this plugin broke my site. I'm not sure if I chose right version of WordPress I'm running because I can't get into my site now, I got this fatal error
Fatal error: Call to undefined function get_current_screen() in /home/content/89/11664089/html/wp-content/plugins/wp-e-commerce/wpsc-admin/includes/product-functions.php on line 23
How can I fix this?
I'm a complete tech novice, please keep this simple!! Thank you
