Nonce has been resolved(FluentCRM)

Hi,
As you can see in the picture, when I try to set up a new campaign in FluentCRM, I get an error called “None has been resolved. Please try again” and another pop up with an “Error: Cookie Check Failed”.

Is there a way to resolve this?

Here is the link of the error pic:
