Webpage views plummit due to Google Friend Connect

So I was playing with Google Friend Connect the other day.

It looked very nice, and I decided to implement it on one of my website. This website attracts quite a lot of visitors everyday, and also generates most of the Adsense income.

Fast forward one week further ad one of my colleagues send me an email telling me there was something wrong with my website.

So I fired up Google Analytics and it quickly became apparent that there was a problem indeed.

Google Analytics Overview

Apparently the Google Friend Connect code don’t like Internet Explorer 6.0, and instead of displaying my page, an error was displayed.
After removing the code, the visits went up again.

So it shows that you really need to test new code on a wide range of operating systems and browsers for compatibility issues.
