WP Live Edit is WordPress plugin that enable the user to update the content, live, on the blog.
This i probably because WordPress insert some other then just the content of the blog. E.g. Like-buttons, rating-widget. If this happens you need to change theme, modify theme or disable just that field.
You need to inspect the title- or content-field. If you use Firebug, right click on the title and click Inspect with Firebug. Look for ...class="entry-title" or ...id="post-title". If you identify by class use the . (dot) else if you use id use the # (hashtag).
No. But for other themes you need to specify which fields is the title and content. See the question over.
Earlier version had problems with some themes. Update the plugin and try again.
