Joomla articles not updating

I was adding a new div in joomla articles but whenever i saved or applied the changes, all my changes reverted back and the div was lost from even the html source of the article. I spent almost 3 hours searching n trying different stuff.

The problem was that joomla articles dont allow empty divs

so:

<div class=”abc”></div>

would never show up neither be saved in the code

so i changed it to

<div class=”abc”>&nbsp;</div>
