I have tried the Chat with Us/Live chat in multiple browsers and it always reloads the main help page.
Sorry you are having issues loading the chat window! Make sure you don't have pop-ups blocked on your browsers as the chat window is a pop-up window. You can allow Constant Contact pop-ups by following these instructions. If you still have issues after allowing the pop-ups, you can also check these other possible browser settings.
Please let us know if there is anything else we can do for you.
I'm sorry that didn't function for you either. I would suggest trying the troubleshooting steps listed here. If that doesn't work, send an email to us at social_support(at)constantcontact(dot)com with a reference to this post. Include your username, the web-browser version, and operating system you're using, and any other information you can give us. If you're getting any error messages, those would be very useful as well.
