Hi,
Pls go to cPanel.
Go to CGI
Select PHP5.4 (single) php.ini
Once the htaccess is changed it would solve the issue.
I believe you have not disabled all your plugins.
The updates conflicting with your plugins as javascript is not loading from the very outset. I think you will have to upgrade TinyMCE or get rid of it.
Hope that helps.
Just click on any link in the CMS. The upload will cancel by itself.
