Hi,
When I try to create a new newsletter using the 'eNewsletter' plugin I get this error message:
Fatal error: Call to undefined function get_current_screen() in /home/content/p3pnexwpnas04_data03/38/2440238/html/wp-content/mu-plugins/gd-system-plugin/class-gd-system-plugin-admin-menu.php on line 235
What needs to be done to fix?
Thanks
