samcolledge on "500 Internal Server Error"

Hi,

I was just trying to change the first page that loads up to my home page. I edited a permalink to say http://www.samcooledge.com/home, as this was my home page.

After doing this I got the '500 internal server error'

This shows up at bottom too 'Apache Server at samcolledge.com Port 80'

Not sure what this means.

Can you help me please as every time I click on something I get this error.

Thanks

Sam Colledge
