Now its working. Thanks for your help.

Hey there,

Thanks for quick reply. I can see that you have removed constant table name from plugin’s main file.
But As of now I am not able to update the Events.
While debugging, I have found this.
$wpdb->$wpdb->get_blog_prefix().WP_SPIFFYCAL_TABLE in spiffy-calendar.php file.
It should be $wpdb->get_blog_prefix().WP_SPIFFYCAL_TABLE

Anyways shortcode is working now for Subsite as well for ajax.

Thanks
