Updated the theme causing issue with xml in blogger

Changed the theme because I can,
forgot to check my customisation that I put in before
google's code says use

<script src="https://google-code-prettify.googlecode.com/svn/loader/run_prettify.js?lang=css&skin=sunburst"></script>

which causes a xml error where the delimiter ; is missing

change
& to &amp;

<pre><script src="https://google-code-prettify.googlecode.com/svn/loader/run_prettify.js?lang=css&amp;skin=sunburst"></script>
</pre>

sigh.. 40 mins lost
