Problems with sub domains

Hi, when i create subdomains they appear in the subdomain folder but cannot be accessed on the web, any idea what the problem could be?

I did look through previous posts and i did check the daemon is running.

can you follow and check logs ?

make sure your apache configs are as they should be.
your problem seems an apache config and ehcp's configs that are included in apache2.conf

apachehcp.conf -> does this include your subdomain ?

check these.
