The error message is telling us that the editor does not have permission to talk to the necessary file. In other words the editor is trying to access a file but your servers file permissions are not allowing this to happen.

Why is this error happening?
Joomla recommend 755 and 0644 for folders and files respectively with suPHP installed running on PHP & MySQL 5+ which gives us a level playing field to work too. However, you may be using a different configuration may need to use 777 for your files. Then again some configurations will not permit you to use 777 (which could be your problem)!

The point being is that Joomla like our editor needs the folders and files to be read/ writable and the entry points for the browsers (this being the file which your browsers need execute) such as the File browsers connector.php file may need be read/write and executable (depending on your server).

How to perform quick diagnostic test

You can check to see if this is happening  by installing Firebug (which is a 3rd party extensions for Firefox - addons.mozilla.org/en-US/firefox/addon/1843/ ). Once installed you can open up Firebug > Enabled the ‘Console’ Tab, visit the page where the error is occurring. If it reports something similar to the error as described above you can be asured that it is due to a file permission issue.

What should I do?

I would recomend contacting your hosting provider and ask them what the correct permission should be for your server? Some may make the change for you, if not then, you will have to use an FTP program and login in to the location of your Joomla site and change permissions directly on the server. Alternatively, if you are a Business & Commercial subscriber we will be happy to make the change for you.
