Firefox : Reloading in a way that ll never complete.

I've been installing Elgg on my server. It is a wordpress blog, I created a dir and tried both. Elgg 1.6.1 and 1.5 Both didn't work. What i did after complete with .htaccess and settings.php! It always occurs an error of firefox that says It's reloading in a way that will never complete. Any suggestion?
