Certain modules crashed web services

Question

I think I'm setting a record here for most questions asked.
I wanted to add a php script to one of my sites (I've been hosting two), so I went into the modules to enable php. While I was in there, I enabled virtual hosting, even though the sites have been working fine without it enabled (I thought I'd need it in the future). I saved the changes and then went online. One of the sites is my homepage, so I noticed right away that safari could not connect to the server. I tried the other site and it was the same. I went back to server admin and discovered web services was off. I tried to restart it and it wouldn't. It suggested I check the log for details (that was no help; I'll paste the logs here at the end of the message). I flew in to a panic and disabled the modules I had enabled and it still wouildn't restart. Then I really panicked and disabled almost all the modules (I know it was stupid, but I was freaking out). Of course that didn't work, so I tried to recheck all the ones that had been checked. Still nothing. I didn't think it would matter since it happened after I enabled php and virtual hosting. I'm at a total loss, and still in a panic. I also tried rebooting the server but that was really just wishful thinking. The logs are pasted below in the following order: system log, site error log. Actually, now the system log is saying something different than it did before. Last night, it was saying "see httpd log." Thanks in advance for any help anyone can give. Here they are:

Answer 1

Turn off the virtual hosts module. It's used for automatic hostname-to-directory mapping so that you don't need to build a complete virtual host configuration file for each virtual host. If you are using Server Admin to build the virtual host configs you don't need the vhost module.
