We just built an ispconfig environment running the latest version of Ubuntu. All pathing seems to be correct, but we are still unable to run any simple tests. For example, if I run the following below: <?php //require_once "Zend_Loader.php"; try { echo 'test start'; Zend_Loader::loadClass('Zend_Session'); echo 'test good'; } catch (Zend_Exception $e) { echo "Error message: " . $e->getMessage() . "\n"; } ?> I see the test start, but I never see the test good or an error message. The system appears to never run the Zend_Loader or provide an exception. I turned on debug level logging, but still there is not error messages. I was wondering if the suhosin potentially causing this problem? Which log files should I be looking at to find why the Zend_Loader is not executing? Thanks,
