'Restricted access' in Joomla

The web guy that ran a site of mine left yesterday and coincidentally my website is down now. It is a Joomla site, and the backend seems fine, but when you try to pull up the site all you see is “Restricted Access”. Can anyone give me an idea of how to fix this? Thanks in advance!

Were you able to fix this problem Ian? (I’m assuming you did being that you couldn’t have your site down for 3 months). I ran into a similar issue when building a template recently. What I had done was over-write the original index.php file in the home folder and to fix this, I simply replaced it with an index.php file from a working site. If worse comes to worse, you simply create a fresh install of Joomla on a test server and yoink the index.php file from the main folder of that.
