4.5.0 update broke previous shortcodes?

Hi Vlad,
Using codes like [su_posts author=”bartleby”] no longer work after upgrading today to 4.5.0
See http://sexncare.com/Bartleby
No errors, the posts simply don’t display.
Also when I attempt to insert a shortcode, the preview does not work, and pressing the Insert button does nothing.
Is there a way to downgrade to the previous version?
Thanks.
