WP admin page errors

I have two websites through wordpress that I have recently not been able to access.
hoffmanautolp.com & moonperformance.com
Both sites function properly as a customer facing site, and we are still receiving information through contact forms, but noticed that the blog posts at the bottom of the page display explict information in the thumb nail of the blog posts but once clicked on the original blog text appears

When we attempted to log in to fix this issue through the wp-admin the Hoffman site displays a critical debugging error and the moonperformance site says page not found.
We have also tried logging in to wordpress.com. the hoffman site says the email doesn’t have an account and the moonperformance site no longer shows up under “my sites”

Both sites had been accessed within the past couple months.
Any information is appreciated
