I think the problem was Arvixe, I set the public_html folder to PHP 5.4 and it worked again, the problem is it's asking for my database information again like its a new install.
I think I messed up the upgrade process. What I did is deleted app, content and lib folders, including .htaccess and index.php then reuploaded 3.5.0 files.
I just found out that I deleted settings.php as well. Good thing I backed up.. I reuploaded settings.php again on app folder then upgrade process worked.. wew
