Sorry Acorn, wasn't being obstructionable.

Really there's three steps to do after you've amended your xar/web file:

1: Save the xar/web file

2: Export (re-export) the Web Document

3: Publish the website.

In other words, if you don't re-export the web document after amendments you're just going to keep re-publishing the old site. Is that clearer?

So yes you were correct but step 2 needs to be done and I missed out step 3
