Constant Contact Plugin Error

Hello,

Today I tried to install a Constant Contact plug and got an error message (sorry I didn’t capture the exact wording). Now, my site is complete inaccessible, I can’t even get to my WP login page to get to the dashboard so I can try and fix. I’m just seeing just many error messages (see below) when I try to login in or even just going to our URL (https://thewritepeople.biz). Can anyone help? Thanks so much. I’m desperate.
