Whats Wrong
Joomla articles not formatted properly when I copy text from my wordprocessor.

REASON
The problem can be caused by copying and pasting articles directly into a joomla article from Microsoft Word or a similar wordprocessor. When you copy text from an article (example Microsoft word) you are also copying the code which formats the article (colors font styles etc). It is this code which is causing conflicts with the Joomla article editor and not allowing your articles to be formatted correctly.

SOLUTION
When you want to copy an article to Joomla it is best to do it this way to remove any formatting code thats attached to the article.
1: Copy the text you want to add to your article (example: from your word processor) and paste it into notepad. By doing this all the formatting code is removed.
2: Now copy and paste the text from notepad to your joomla article and save it. Your article should now be formatted properly.
