TinyMCE Broken

Hello,

My Visual editor was still working this morning. But when I upgraded to WP 4.5 this afternoon, I can’t see my visual editor anymore. The HTML(text) editor is fine though.

I tried deactivating all my plugins, it did not work.
I tried to reinstall WordPress, not working.
I replaced they copy of tinymce from older WP version, it did not work.
I did manual install of WP, it did not work.
I added this: define('CONCATENATE_SCRIPTS', false); in wp-config.php, it did not work.

Your help is highly appreciated.

Regards,
Eli
