thanks. It seems to have resolved itself in the meantime (suggesting that it was indeed a cache issue somewhere).
Same issue. I can make it come back by changing the ‘add_action’ back to ‘comment_form’. i.e.
add_action('comment_form_after', 'lcp_add_preview_div');
goes back to:
add_action('comment_form', 'lcp_add_preview_div');
Possibly a change in the calling string in comment.php would work too.
Follow on: I’ve just updated to the latest version (2.01b), and although the changes make this more robust, the preview does not recognise URLs ending in a digit still.
i.e.
<a href="http://abc.com/1">fred</a>
does not get rendered as a link in the preview.
