Unable to get error messages on linux

Hi All,

I've got a strange problem.

In the follow I assume the all of you have used the test class saprfc_test.php

When I use the rfc library on a Windows server, if the data are wrong (the username the password the host ect) I got a error message with describe the error.

I made the same installation on Centos5, Ubuntu 8 and Fedora 9: it works fine only if the data are correct. In that case I can call successfully any bapi I want. If any information is wrong I don't get a error message. Simply the browser load a blank page.

Have you any idea of this weird behaviour?

On unix are you able to get error messages with the saprfc_test class?

Thank you very much

Massimo
