Please check your article and / or resource boxes to make sure you have included ONLY the following html tags:

<b>
<u>
<i>
<strong>
and correctly formatted hyperlinks

This means that these are NOT permitted:

<p>

<br>
<div>
<span>
<script>
<table>

and any other instance of either < or > - That means you cannot include arrows such as ==> or -->

Most likely you have included one or more of the above :-)


Why are all these excluded? There are three reasons:

1. Website owners don't want you to be re-arranging the appearance of their site by including a whole bunch of style changes.

2. Broken html can totally destroy the display of a page.

3. There is a serious security risk if we allow html tags through. This is known as cross-site script injection and can allow criminals to inject malicious code into other people's sites leading, among other things, to identify fraud etc.
