Jason, my bad. I upgrade to the latest version of Design Extender and followed instructions from the Cowboy in terms of 4 or 5 directory replacements. Login into CMS everything is working fine. I add a link within CMS to a file in the files directory and I get a Server 404 error. The file is there, I have confirmed that and the syntax appears correct. Seems like there is a security restriction on this new link. I have similar links above they work but they were initiated and completed prior to the upgrade.
