PHP 500 Internal Server Error

Today I encountered an error message in the integration test with "500 Internal Server Error". I have wasted an hour in searching the "Client-Warning: Redirect loop detected" in google and playing around with the require statement etc.

The easiest way should be just turning on the error logging in php.ini, log_error = On. The error message in the log told me the require statement couldn't find the target php file. That's it...

PHP Fatal error:  require_once() [function.require]: Failed opening required 'utilities.php' (include_path='/opt/ecloud/i686_Linux/php/lib/php') in /opt/ecloud/i686_Linux/apache/htdocs/accelerator/evalPhp.php(18) : eval()'d code on line 2
