I believe I've used this plugin before. Sometimes it would say "no data" after I moved things around or installed/unstalled plugins and widgets. What do you mean by "all time tab" only? I don't read Spanish well. It seems you have tabs for latest, popular and best. There seems to be a message like "Sorry nothing to show here" in the popular tab, but there are three posts displayed there.
It's been so long since I worked on the site that I used it in, I can't recall its features right now. Are you looking for like "most popular today," most popular this week," etc.?
