  • Hi,

    After installing your plugin, I get a this error.

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘xeroom_display_message_if_licence_not_valid’ not found or invalid function name in /var/www/stream-book-shop/html/wp-includes/class-wp-hook.php on line 286
