Strange Civi errors when editing contacts

Question

When editing contacts in Civicrm i've been receiving one of two errors, I'm worried these are going to cause further issues down the line.

-An error with no error message:

Answer 1

-An error with no error message:
The error looks like the user is not logged in. Did you faced the problem after logging out and logging in?

Could not find valid value for ct code: This happens when 'ct' (contact type) param is missing is url. Usually happens when you try to visit the New Contact form and you are log out and then after logging in you might face this type of error.
