Why I get a Parse error: syntax error on upload theme/plugin ?

Did you use FTP to install the theme to your server? If yes then your FTP software messed up the mark up of the file.

In that case, delete the theme from /wp-content/themes/ folder and then install it using the Theme Installer, following this tutorial: http://docs.themeisle.com/article/4-how-to-install-wordpress-themes
