I'm an italian girl and i don't speak (and write) english very well so i start whit excuse for the mistakes that i'll certainly do!!

I've tried to install the new version on Joomla but i think i do a b******t!!

I've followed the instruction that i found in the italian manual of Joomla but now every action that I try to do opens a blank page and a message like this: "Fatal error: Call to protected method JRequest::_cleanVar() from context 'FOFInput' in /home/uvfqtah5/domains/frimax.it/public_html/libraries/fof/input.php on line 30"

Please help me!! What i have to do?

Sorry again for my english :(
