Just take data-cfasync="false" and paste after <script so you end up with this for example:
PHP Code:
<script data-cfasync="false" type="text/javascript" src="clientscript/vbulletin_read_marker.js?v={vb:raw vboptions.simpleversion}"></script>
I actually think the issue is minifying the javascript at the same time you use Rocket loader that is causing the cpanel to refresh..
