I have installed xampp on ubuntu. PHP is configured to show all possible errors, warnings, notices etc, but when i make an error in php code no error is displayed. 

When i copy that file to other computer (debian with native apache, mysql and php set) and open it in browser it shows 

```
Fatal error: Call to a member function fetch() on a non-object in... 

```

as expected, so why xampp with identical php.ini shows just an empty page?
