Hi Andrea,
As Sherif said, a link so we can check out your code would be the easiest. If that's not comfortable for you, try this: Remember, most outside links, such as ezinearticles, will have code in more than one place in your page code. You may have removed only part of it. Go through the entire code and look for something similar to this.
<a href="http://Ezinearticles.com/" target="_blank">
<img title="Visit Ezine articles" alt="Click here for Ezine Articles" src="http://EzineArticles.com/whatever our button is.jpeg or .gif" border="5">
</a>
Make sure all that is gone and also, if you have an image of the button in your site folder (not sure if they host it or you do, it varies) remove that as well.
If that doesn't work, we'll try something else.
Hope that helps.
