External SOAP script / issue with global.php

[VATSIM-CH]

Hello guys
I hope you can help me out.
Since vB4 my SOAP-Script isn't working anymore.

The Idea is:
Another Homepage should be able to create postings/threads and maybe also change a user (username).
I built a SOAP-Script which will then include the VB-Functions with the datamanagers and so on. But everytime when I start to include the "global.php" it looks like there is an output from this script, as my XML-Output from SOAP gets invalid and/or the error "uploaded files to big". As it is only text for a thread with no files, I think there must be a huge output from the vb-script.

Actually I'm running out of ideas how to get it working again.
Or do I have a wrong approach to get this work done?

Is there another "easy" method how an external script can create a thread or post into threads?

Thanks in advance for your help
Mike

The error messages:
SoapFault exception: [Client] looks like we got no XML document

The file(s) uploaded were too large to process.

I'm not sure I understand what's going on, but I can't think of any reason that global.php would output a large amount. Can you show us at least the beginning of your script?
