Since upgrading to 3.5 (also with 3.5.1) in FF, Chrome and IE I am having problems with the editing screen. This is on different WP installs on two different webhosts.
The buttons to swap to code mode and that to insert a hyperlink fail to work when clicked.
When I switched on the error console in wp-config.php the button for code mode began to work, but not that for links.
It throws dozens of error messages beginning with:
s3.amazonaws.com : server does not support RFC 5746, see CVE-2009-3555
Can someone help me work out what is wrong?
