for some reason I cant add a sidebar with widgets except the one on the tab you can find here http://en.vif.com.mx/site/ (under the subscribe tab)
So I added this
[wpp header_start="<h2>" header_end="<h2>" post_type=post cat=182 order_by="views" title_length=25 excerpt_length=55 range=monthly limit=12 post_html="<li class='lista'>{thumb} <a href=\'{url}\'>{text_title}</a><br /><p>{summary}</p> </li>"]
and after emptying cache... well you can see how it shows.
The things is that it used to work before, and nothing changed since :/
