Hi Martin,
Thanks for getting back so quickly. The reason for Invalid or expired token on the test site was that I hadn’t updated that site with the new APIs (though the problem was still occurring on the live site). Your question of “Are you doing this with a shortcode or a widget?” prompted me into looking at how the webdesigner had set it up on the new site. I discovered that he had installed the widget but had put my name Chris White into the Twitter Name field instead of @MrChrisGWHite. Having just corrected this, it all seems to be working and my public site is now live again with the correct feed.
Many thanks for your help with this and the great widget. Donation on its way…
BW,
Chris White
