Cleaning the home screen

Hello, is there a way I can wipe out the the home screen? Because, for some reason, some of the blank spaces in my homescreen are ocuppied, I can´t put any apps or widgets on them, even when they are blank. Thanks.

:? That's very odd. I don't know of any ways to do that without root, unless you switch launchers.

Thats weird, maybe you have widget that looks like it only takes up a tile or 2 but is longer?

What phone and version are you running?

The widget that was in the space was the Youtube´s. I own a Sony Xperia Arc in 2.3.3. I already tried uninstalling the youtube app, no avail.
