I sent you a mail about this before too. I am using the live support software from cSupportHQ but when someone tries to chat with me the chat header isn’t showing properly. They told me it’s an issue with the css. I put an image and the link to my website in the mail.
Here is the website, http://goo.gl/0aPM41. The chat bar is only showing when I’m online, I sent a picture to your support email address. When I look on the css in Firefox, it’s the overflow, I just don’t know how to change it.
