Moved site, theme doesn’t work

I moved the WP site from one server to another. After the move I got nothing but a blank screen. I did a view source of the “blank” screen and there was a small amount of header code but that was all. Gleaned the forums and saw where someone suggested I try deactivating modules and revert to the Default template. Reverting to the default template “resolved” the blank screen but I’m at a loss as to what could make the theme not work on the new server. I’ve double checked and made sure all the files got copied over. The ownership “seems” to be okay, but in all honesty I’m really not sure what I need to look for here, since it worked just fine before I moved it.

Thanks!
