I noticed an update was available today. I upgraded two sites to test (5-6 files were changed) and now these sites just display the background template and nothing else in both browsers. But I can access tpupdater.php and updater.php. I was just wondering if some update is on the way or if I need worry about getting hacked? If you are rolling out an update you may want to check it since it did this on two sites.
Update:
It looks like it does it every time I upgrade to the ioncube version. The latest version I can use without the problem seems to be v.35.
Even though it worked before and ioncube loader v.4 is definitely installed and working here is 'php -v'
Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies
with the ionCube PHP Loader v4.0.0, Copyright (c) 2002-2010, by ionCube Ltd., and
with Zend Optimizer v3.3.9, Copyright (c) 1998-2009, by Zend Technologies
My other installs which are using v.41 (ioncube) are working fine but they show an update available.
