Front page always showing the same article

[dulfu]

i have a blog, ​http://blog.farmaciadulfu.ro in settings/reading is selected "your latest post", but in the front page of blog, is showing always the same article, no matter if i publish another one or two new articles.

Right now the front page is showing "Nasterea naturala declanseaza proteine care imbunatatesc dezvoltarea cerebrala" article, created in 23/08/2012, despite the fact that are another five newer articles, from 24/08/2012 to 31/08/2012 .
I attach the admin.jpg, showing the setting for "reader" and the front.jpg, the frontpage capture.

Yes, that's how sticky posts work: ​http://codex.wordpress.org/Sticky_Posts

If you don't want the post to be sticky, uncheck the corresponding checkbox under Visibility settings in the Publish box on Edit Post screen.
