Okay…
I disactivated all the plugins… and activated them one by one testing, except the automatic upgrade… And the page showed again without error. However the dashboard still had the class-snoopy error inside the incoming links section adn the others underneath didn′t showed… So uploaded again the class-snoopy.php file and now works…!!!
I also upgraded the automatic upgrade plugin but still is messing things up… so I guess I had an ftp upload problem of sorts, because they claim they fixed…
So thanks again!!!!
