Not all virtual hosts work - ispconfig/apache

[dmtrotter]

Hey all - This is the first time I have posted here. I have been running ispConfig for quite a while now with only a few issues I was able to figure out and fix on my own. Now I have an issue that I just cant figure out. Here is what is happening:

I am hosting 4 domains currently on my Ubuntu box using ispConfig. I added a 5th domain today after registering it a few days ago. After configuring it, and adding mailboxes (that all all work), I decided to test the site itself. When I try to browse to the site via domain name, I get the Internal Server Error 500.

I am still able to get to ONE of my other sites, but the other 4 are completely inaccessible. I have not installed anything new on the server for quite a while, and everything was working after the last install I did perform.

Please help!

Thanks in advance.
