If you're getting the 404 error - it's most likely one thing - you don't have modules compiled into apache.

Is this your box or someone else hosting it for you?

Go to your admin panel - Maintenance - View PHP Info

Under the section apache2handler there is a Loaded Modules Block.

In there you should see mod_rewrite - without that! It's a no go!

If you have access to the box you can check the conf file and try adding
LoadModule rewrite_module modules/mod_rewrite.so

Just add it underneith the loadmodule line for php. Restart apache and check your php info again - still no go the original compile did not specify modules and you'll need to recompile.

This site is hosted by someone else. I was unbale to find the apache2handler section and the Loaded Modules block. Does that mean I'm just screwed
