Visual Editor not appearing Working, wordpress 3.8.1

Hi,

I know this is a common problem, as I read and tried almost everything on every thread posted about this same subject.

I am running WordPress 3.8.1 (not an upgrade, as it was a fresh install and new site) and the visual editor button shows up on the page/post pages, but when clicked (it shows the hover state) nothing happens. Same for the add media button, can be clicked, but does not “insert image into post” when clicked.

I have tried the following with no avail:
-made sure that “disable visual editor” button under users in NOT clicked
-deactivated all pluggins
-switched my theme to 2014
-I have, via FTP, deleted and re-uploaded new files of wordpress 3.8.1 wp-admin and wp-includes
-I have added define(‘SCRIPT_DEBUG’, true); to my wp-config file.
-Added define(‘CONCATENATE_SCRIPTS’, false ); to wp-config just after WPLANG line
-cleared cache, restated computer in Chrome, Safari and Firefox
-double checked that javascript is running

When I check on my console, I am getting the following errors:
Uncaught TypeError: Cannot read property ‘canvas’ of undefined
qt.closeAllTags quicktags.js?ver=3.8.1:555
window.switchEditors.go editor.js?ver=3.8.1:40
window.switchEditors.switchto editor.js?ver=3.8.1:11
onclick

Please let me know if anyone else has any suggestions. I feel like I have been running in circles with this for two days. Thanks so much!
