Thanks @Wes. I had thought of that too, but what confused me is that all three footer text widgets are formatted the same as the first one, yet it’s only the first one that loads incorrectly aligned. Footer text widget one reads:
<div class="textwidget"><blockquote style="margin: 0;">

<h6>Artemis is a professional consultancy with broad project management experience in all aspects of quality publishing. We offer creative publishing solutions and love what we do — we're confident you will too! </p></blockquote></h6>
</div>
Which bits should I delete — and I assume I should edit the remaining two text widgets to match?
Many thanks,
Susie
