How do I fix the wysiwyg editor's background problem

Some of Joomla templates can cause a conflict by applying site's backround as the wysiwyg editor's bacground also.

To fix this issue, add this to your joomla template's css file:

* TinyMCE specific rules */
body.mceContentBody {
   background: #FFF !important;
   background-image: none;
}

The fix is sometimes not visible immediately, clear browser's cache and check it later.
