Jump links stopped working



Jump links to one of the pom blocks on the page suddenly stopped working on this site: https://masterclass.symbid.nl/ (links in the top of the screen).

I’ve tried custom html links as well as buttons but they all give the same error in the url “?aid=undefined”.

Thanks in advance.

Kind regards,


Hi @Maikel,

It seems that you have added a script that appends “?aid=undefined” to all links on the page and that’s causing your issue.



Hi Hristian,

Thanks for the response.
That’s weird. Where can I find this script? It’s not in the script manager (general or page scripts).


Hi Maikel,

If it’s not coming from Unbounce check your Tag Manager. It’s being loaded from somewhere :slight_smile:



Got it. Thanks
