TWTR.Widget throws "unsafe javascript attempt to access frame" for search


I have been using the TWTR.Widget for a long time on my production site. Early this week, everything was working successfully. Today, the widget is throwing the exception “Unsafe JavaScript attempt to access frame with URL from frame with URL about:blank. Domains, protocols and ports must match.”.

Does anyone know why this would start happening? I’ve checked our internal version control system, and nothing has changed.

I would give an example of the error on my site, but the entire site is behind a paywall. Here is the script code:

  <div id="TimelineWrapper" style="position: static;">
      var oTWTR = new TWTR.Widget({
        version: "2",
        type: "search",
        search: g_cShowDefaultValue,
        interval: 5000,
        rpp: g_oTwitterParams.iSocialMediaTwitterRPP,
        title: g_cMessages["SearchingFor"],
        subject: g_cShowDefaultValue,
        footer: g_cMessages["Join"],
        width: 'auto',
        height: g_iHeight,
        theme: g_oTwitterColors, 
        features: {
          scrollbar: true,
          loop: true,
          live: true,
          hashtags: true,
          timestamp: true,
          avatars: g_oTwitterParams.bSocialMediaTwitterDisplayAvatars,
          fullscreen: false,
          toptweets: false,
          favs: false,
          behavior: g_oTwitterParams.cSocialMediaTwitterBehavior

Thank you,



I am also getting same error suddenly.


Also getting this. Anyone know why?


Good day,
I’ve been doing research on this and found out a little (undocumented) tricky bit. If you are using the _play method on the TWTR.Widget, you MUST call the start method first. I believe that my issue was a timing issue where the dymanic loading of various things caused _play to be called before start (caused by an infrastructure change). When I ensure that start is called first, the error does not happen. When I ensure that start is never called, the error always happens.

Hope this helps,
