I upgraded a customer's site this morning from 184.108.40.206 to 220.127.116.11. After the upgrade, the front-end and back-end would load part of the page header but nothing else.
I am sharing the root cause here for anyone else who encounters it. In
/html/app/code/core/Mage/Cms/Helper/Data.php, there's a new function
isSwfDisabled(). Older versions of PHP fail to parse it.
$statusSwf = $statusSwf->asArray();
you can use
$statusSwf = $statusSwf->asArray(); $statusSwf = $statusSwf;
Of course, you won't want to change the code directly. You'll want to create a proper override or upgrade to a version of PHP that supports the syntax.
Hope this helps.
