Hi, have run through the steps to set up MAMP & VirtualHostX detailed here: http://seansperte.com/entry/Setting_U...

MAMP works - both Apache and MySQL running but when I try to view virtual hosts I have set up all I see is empty directories (http://dev.mysite.com/) or 404 errors if I try http://dev.mysite.com/index.html

I have tried removing MAMP and VirtualHostX and running through the installation again unsuccessfully.

Any clues where I'm going wrong? I'm a complete beginner so explanations need to be basic!

Thx, Damian
