Errors after running latest updates

I just ran the series of update my WP site informed me I needed to run. After they finished, my home page has error messages all over it.

They state this:
Warning: in_array() expects parameter 2 to be array, string given in /home/content/74/13155774/html/BITLC/wp-content/plugins/social-buttons-pack/bws-linkedin/bws-linkedin.php on line 161

Can anyone help with this? Is it WP or a Plug In? Looks like a plug in update that went bad, but I thought I only ran WP updates.
