Blank Content w/ empty source. index.php exists.

Permalink
So I recently inherited a concrete5 site where a copy/migration from one host to another was in progress. config.php is correct, index.php exists. I've messed with .htaccess as well. Concrete5 is up to date. I asked the guy I inherited the site from where he was in the process of migration and he said that his last step was to "Scouring the DB tables for all url/links associated with the old host and transferring them to the new one". I'm not quite sure what was meant, and am not having luck finding that out. I searched the DB for any references to the old URL but have found none. Any thoughts? Any help is greatly appreciated!!!
