Hi Vitali,
The problem you are experiencing is because your site is https://.
Soon we will apply a fix to this issue.
In order to resolve it for now please copy and paste into your WordPress editor the following code snippet instead of using a shortcode:
<div id=”debate_1_11275″><div class=”os-power-by” style=”width:100%;margin-top:2px;line-height:11px;text-align:left;font-family: Arial, Helvetica, sans-serif;font-size:11px;”>
<div>
social vote by <em style=”color:#33b5e5 !important”>Opinion Stage
</div>
</div>
</div>
<script>
(function () {
var opst = document.createElement(‘script’);
opst.type = ‘text/javascript’;
opst.async = true;
opst.src = ‘https://www.opinionstage.com/debates/11275/embed.js’;
(document.getElementsByTagName(‘head’)[0] ||
document.getElementsByTagName(‘body’)[0]).appendChild(opst);
}());
</script>
Best,
Gil.
