Webcast re-registration

Often, I am unable to re-register for a webcast (in another browser, because the registration cookie lives in a browser without the evil Flash shove-it-through-your-throat-ware) because of multiple JavaScript errors on the page. How can this still not have been fixed after existing for months in a row?

Excerpt from console (Safari, Chrome and Firefox) after visiting :

ml.js:328 Uncaught ReferenceError: jQuery is not defined
(anonymous function) @ ml.js:328
3423:1234 Uncaught SyntaxError: Unexpected identifier
sso.js:5 SSO (Thu, 23 Jul 2015 18:10:39 GMT): checking for session

(BTW, why do I have to re-register after having logged in in the first place?)

  • Hi Vincent,

    I checked in with our webcast team about this and they said
    that you registered for that webcast back on June 22.

    Also, it seems like you are might have something blocking a necessary script that needs to load for that page to work.
    Do you have any script or ad blockers installed?  Or are you on a restrictive corporate network?

    For problems with webcasts, you can always send a note to for a response within 24hrs.
