Additional comments

This is an entirely bizarre error. I have used Google and found this but it's a year old with no solution. I have also tested this on multiple (similar) Joomla sites and got the same error.

This error is nothing to do with tinymce or the core of joomla. It is caused by one of two things

  1. A security plugin that you have installed in joomla - unlikely but possible
  2. the apache web server module mod_security and a faulty rule. There should be a mod_security log on your server to confirm this. If you do not have full control of the server then you will need to speak to your webhosts
  3. Some other faulty security rule that your web hosts have enabled that is triggered by this word.
