Knowledge Tree and PHP 5.3.3

We have got the latest PHP version on Hostsharing, and Knowledge Tree 3.7.0.2 did not work anymore.

I got a long list of deprecated warnings, and the session would not even start, so not even a login screen is displayed.

Deprecated: Assigning the return value of new by reference is deprecated

Warning: The magic method __get() must have public visibility and cannot be static

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent

The solution is to edit config/dmsDefaults.php, find the lines containing

error_reporting(E_ALL & ~E_NOTICE);

ini_set('display_errors', '1');

ini_set('display_startup_errors', '1');

Below that, add the following line:

error_reporting(0);

Now Knowledge Tree 3.7.0.2 will work again, and hopefully the next version of Knowledge Tree will have fixed all the deprecated PHP things.
