I use FileVault on my Snow Leopard setup to protect my precious code. When I turned it on my local apache couldn’t accesss my local test folder of PHP code anymore.
To correct this you need to adjust the apache user in the
httpd.conf. You can find the snippet below around line number 130.
User www Group www
change it to your local unix name
User webpatser Group www
You can leave the group setting. If there are multiple users on the system using FileVault, this is, I guess, not the answer to the problem…
