If you can log in to smartCARS 3 but are unable to do fetch items such as PIREPs, pilot statistics, or your communities news, this may be due to your web host not being able to pass what is called the HTTP Authorization Header.

If this is the case, you may have to contact your hosting provider to confirm if this can be supported. If your hosting provider does not support the HTTP Authorization header, you may have to switch to a provider which does support this.
