Mod Pagespeed Configuration

I asked this question on another site and it's not getting any attention, so I decided to try it here.

Server: CentOS, Apache, WHM/Cpanel, Hostgator dedicated.
I had mod_pagespeed installed and working. Someone at HG ran a script that killed mod-pagespeed and they had to re-install it.
Now, it is installed. If I open our page in firefox I can check the headers and saw the pagespeed header. But, if I search the HTML Source, I have no mention of "pagespeed" anywhere. (I used to see all the image sources re-written to a pagespeed version.)
HG says they don't support PageSpeed, so they're no more help at the moment.
If I visit www.mysite.com/mod_pagespeed_message, I see several messages like:

Initiating async fetch for http://127.0.0.1/banner2/13.jpg

Code (markup):

Since I have several VHosts on this one server, that URL is not specific enough to find the image. I think that's ONE of my problems.
I have root access to the server using PuTTY and know how to use pico/nano to edit a config file, so if your answers require that, I can follow along.
Update: When I specifically added ModPagespeedEnableFilters rewrite_images to my configuration file, it did turn my favicon into a data: uri, but it seems like the other filters fail because it is trying to use the localhost IP instead of the domain name.

 

Hello
I think you already search on forums. However did you try this ? To add on your conf the domain ?
