I am trying to append a div at the end of the content.
I succeed to do so in some wordpress blogs, but others simply do not add the div.
I tested and saw that the my_add_widget function is being invoked in all blogs - but the div is just not appended in some cases.
Example of blog that do succeed to append the div: http://www.mixedwaves.com/
Example of blog that fails to append the div:
$linkToPost = get_permalink($post->ID);
$content .= '<div id="ewidget_'. $post->ID .'"></div>';
Any idea why is that?
