Tutorials: Joomla editor not working
If you're unable to write or modify content in the Joomla administrator area, please logout and login using:
http://yourwebsite.com/administrator - skip the www. part as sometimes the editor will display a blank field, or a disabled one which will not allow you to edit or publish new content because of it. If that is the way you've connected to the website try adding the www. Also try clearing your cookies, cache and temp Internet files. If all of the above fails, please contact us and we'll find out what's wrong.
