DSM interface error from wpintegration.js

Hi folks.

(this was also posted under portal implementation but I'm not sure actually the best forum, sorry for duplicates)

I get the following Popup when trying to reach a transaction in an integrated ITS on SRM 4.0 f r o m the Portal:

WPINTEGRATION.JS could not find SAPWF_sendSessInfo() to send " + curService + "'s SessInfo to DSM.\nPortal's DSM Interface might have changed. ");

WSINTEGRATION.JS is part of BBPGLOBAL ...

This is since we changed the ITS server properties from the Sandbox machine to the Dev machine.

Anyone have seen this or have any tips that would be greatly appreciated.

(The SRM transactions works very well, but the popup is very anoying obviously)

Best regards and thank you very much in advance.
