Thanks for the pointer, no requests coming through apparently, so it must be a javascript problem. But I am using exact same settings as was in the source (\Clients\PortfolioDemo_online) - obviously changing the port/hostname/domain values. One thing the source did not provide was the 'base' js/html files but I just used the ones that came with the server distribution (\DOCS-SDKs\sdk_client_web\lib).

Not sure what else I need to add? There is no javascript popup msgs, and although the browser status bar reads 'Lightstreamer is connecting...' nothing is displayed in the table rows

At the moment I have index.html, lsengine_config.js in root web folder with the ls html/js files in /ls/lsblank.html etc (6 files unchanged).
