The HTML you inserted into the text widget contains error:
<a target="â€_blankâ€" href="â€http://lata9.glutenfabs.hop.clickbank.netâ€">
<img border="â€0?" src="â€http://www.glutenfreewaytobe.com/wp-content/uploads/2013/02/gluten_free_abs.jpgâ€">
</a>
Each of the attribute value (e.g. "_blank") has additional double quotes that shouldn’t be there. This is likely to be because you copy-pasted the HTML from a source that formats the double quotes into a “pretty” double quote (notice how the inner double quotes differ from the outer double quotes) instead of a plaintext double quote.
It’s supposed to be like this:
<a target="_blank" href="http://lata9.glutenfabs.hop.clickbank.net">
<img border="0" src="http://www.glutenfreewaytobe.com/wp-content/uploads/2013/02/gluten_free_abs.jpg">
