Just upgraded to 2.2.3 but have database errors

I just finished my upgrade to 2.2.3, but I get a database error that appears at the top of my web page. My website is https://www.sinisterhand.com and the error is pasted below. Any help would be greatly appreciated.

WordPress database error: [Specified key was too long; max key length is 1000 bytes]
CREATE TABLE IF NOT EXISTS wp_bdprss_items (item_feed_url varchar(240) NOT NULL, item_url varchar(255) NOT NULL, item_name varchar(255) NOT NULL, ref_number int(5) NOT NULL, text text NOT NULL, item_time int(15), item_update_time int(15) NOT NULL, PRIMARY KEY (item_feed_url, item_url), INDEX feed_index (item_feed_url), INDEX update_index (item_update_time), INDEX time_index (item_time) )
