WordPress-3.8.3 does not upload properly with FileZilla

Hi guys,

I am using FileZilla FTP client. And this is my first time trying to upload wordpress-3.8.3 under /public_html on my website.
The website was fine before I uploaded wordpress. Once it’s uploaded I got “Internal Server Error”. It seems that both wp-includes/js/tinymce/plugin and wp-includes/js/tinymce/themes folders cannot be found by FileZilla?

My FileZilla FTP client setting:
– Port: 21098
– Protocol: SFTP
– Mode: Passive
– Maximum number of simultaneous connections: 1
– Server Type: Default (Autodetect)
– Directory: “/public_html”

Error messages:
– Directory /home/’my cPanel username’/public_html/wp-includes/js/tinymce/plugins/inlinepopups: no such file or directory
– Directory /home/’my cPanel username’/public_html/wp-includes/js/tinymce/plugins/media: no such file or directory
– Directory /home/’my cPanel username’/public_html/wp-includes/js/tinymce/plugins/paste: no such file or directory
– …etc.

– Directory /home/mornhyzb/public_html/wp-includes/js/tinymce/themes/advanced: no such file or directory
– Directory /home/mornhyzb/public_html/wp-includes/js/tinymce/themes/advanced/skins: no such file or directory
– …etc.

If anyone has any idea, thank you very much in advance!
