Locked out of Website due to faulty plug-in

I am unable to log into the admin account to make changes to my website. It appears the Ocean Extra plug-in is throwing errors and printing them at the top of my website (see website for evidence). I had previously updated my WordPress to the newest version.

Please advise how to disable Ocean Extra in order to access my word press account while simultaneously being locked out of WordPress.
