Okay i have some problems with it.

1. Once i installed ligthttpd, it created a folder /wwwPHP and i guess in your case, you have /var/www/ already. However, i just used the wwwPHP folder and continued with installation.

2. Lighttpd doesnt start at all (when i try to access it via browser, nothing comes up but i can ping my phone). I also tried to access it local via MicroB but it says same as Mozilla on my normal computer "cant establish a connection to the server at 127.0.0.1 (or 192.168.0.172)
