Today i just upgraded one of my wordpress site to 3.3.
After croscheck anything i found that my wordpress visual editor have a problem and the toolbar also not showing.
After googling for few hours i found the solution.
1. disabled all your plugins [optional]
2. reinstall your wordpress [ optional]
3. edit wp-config.php
The solusion is very simple, we just need to add 1 line into wp-config.php like below :
$vi /home/testing/public_html/wp-config.php
### add 1 line below ####
