Please not just two columns and the search box acting up.</p> <p><img src="https://i.stack.imgur.com/rg4P9.png" alt="BROKEN"></p> <p>Developer tools in Chrome and Firefox show no errors. No missing files. No nothing. I got the assets on Server 1 to point to Server 2. Still worked. I got the assets on Server 2 to point to the assets on Server 1, still broken.</p> <p>Any ideas? Exact same code, on the exact same server setup (Windows 2008 R2). With that said, could IIS be doing something?</p>
