"This page includes script from unauthenticated sources."
Websites that ask for sensitive information, such as usernames and passwords, often use secure connections to transmit content to and from the computer you're using. If you're visiting a site via a secure connection, Google Chrome will verify that the content on the webpage has been transmitted safely. If it detects certain types of content on the page coming from insecure channels, it can automatically prevent the content from loading and you'll see a shield icon appearing in the address bar. By blocking the content and possible security gaps, Chrome protects your information on the page from falling into the wrong hands.
What to do if you see this alert
Parts of the page may not display when Chrome blocks the insecure content. You might want to notify the website owner that their site isn't properly secured, particularly if it does not display properly.
Although not recommended, you can choose to override the alert for the page by clicking Load unsafe script. Chrome will refresh the page and load its content, including any insecure content. The URL in the address bar will show to indicate that the page is not fully secure.
