[Plugin: Analytics360] AuthSub target path prefix does not match the provided "next" URL.

I’ve activated my MailChimp account through Analytics360 and it works fine, but I just keep getting error when trying to authorize Google Analytics in my dashboard.

The error I get is this:

The page you have requested cannot be displayed. Another site was requesting access to your Google Account, but sent a malformed request. Please contact the site that you were trying to use when you received this message to inform them of the error. A detailed error message follows:

AuthSub target path prefix does not match the provided “next” URL.

How do I fix this?
