Blank popups in Joomla

If you are using Joomla and your popups come up blank (for example, the add a link window or the HTML window) here is a solution.

In the configuration.php file, edit the $mosConfig_live_site line so that it reads ‘http://www.yoursite.com’ instead of ‘http://yoursite.com’. In other words, add the www to the URL.
