Yep received email from GoDaddy this morning with same info as below to fix. This solved my issue!
It appears that a recent upgrade to Apache 2.4 has caused mod rewrites (redirects) to function in a slightly different manner that is effecting how Silver stripe is redirecting. In turn, this was causing all redirects to sub pages from functioning properly on your website. I have made a modification to your code that has corrected the issue at this time. The changes within the file sapphire/main.php on lines 76 and 77 are as follows:
**Original Code**:
if (isset($_GET['url'])) {
$url = $_GET['url'];
**New Code**:
if (isset($_GET['YourDomain.com'])) {
$url = $_GET['YourDomain.com'];
