Hi,
Sorry for the issues with the links in IE8. We no longer support IE8 due to Microsoft dropping support and the security risks created from not having that support.
I understand there are still reasons to support it.
So the only way to support IE8 is to turn off the AJAX scripts as that is what IE8 does not support.
This snippet disables AJAX for the Calendar, List, and Day View:

Let me know if you have any follow up questions.
Thanks
