There is a fairly simple fix for the "Internet Explorer - Cannot open the site..." problem that is becoming more prevalent as we experiment with different Javascript libraries and Google API.
In the index.php of the template file of Joomla, there should be a segment of code that calls the Google component config.php through a require function, as well as a Javascript call from Google itself. This segment of code was originally set to be inserted before head section the of the HTML. This insertion, however causes IE6 to abort all functions and not load the site.
Solution: Remove the code from the head section and insert it before the end body tag at the bottom of the file. This will fix the problem.
