I was integrating Twitter updates on a Joomla! site today and realized that whenever I was adding the SCRIPT to the HTML source code it was being wiped out when I would save. Thankfully the fix is easy:
1. Go to Extensions–>plugin manager & click on Editor – TinyMCE 2.0
2. Go to Plugin Parameters
3. Select ” never ” to Code cleanup on save option and save it
If you are using another editor then you’ll have to see if it has a similar option.
Please refer to this link for a thread from people who have struggled with this same problem.
