When I visit a spot and then return to the page I previously was, no actualización appear on it. Is this normal?

I suspect that tu are using your browser navigation (back and adelante, hacia adelante buttons) to mover between pages you've visited. Depending on your browser, this will load a cached version of the page to save bandwidth (most browsers do this). So, if tu weren't doing this already), make sure to navigate between pages por clicking on enlaces in the pages o using the fanpop buscar feature. This should prompt your browser to contact the server and reload the page, rather than cargando... a cached version. As an alternative, tu can force the browser to reload a page (in most Windows browsers this is done por holding down the SHIFT key and clicking the browser "reload" button). One o the other (or both) of these should address your problem. If neither does help, then it is a bug, and should be reported using the "contact us" link at the bottom of any page.
