strange behaviour: text appears below content

I work with Weaver II, vers 2.2.8.
Since yesterday the word “replay” appears below the content area of pages. On blog page it does not appear. Can’t find where this text is stored in. Checked already nearly all *.php. No new plugins nor updates. Some ideas?
Firebug shows this:

<div id="main">
<div id="container" class="container-page">
<div id="content">
<div id="post-759" class="post-759 page type-page status-publish hentry">
</div>
<strong>"replay"</strong>
<div id="comments">
</div>
</div>
<div id="ttw-bot-widget" class="widget-area" role="complementary">
</div>
</div>

Help is really appreciated
