Problem: SharePoint browser-enabled InfoPath form gave this error message:
There has been a critical error while processing the form.
Click Start Over to load a new copy of the form. If this error persists, contact the support team for the Web site.
Click Close to exit this message.
Object doesn’t support property or method ‘addEventListener’
This is due to Browser compatibility settings. Add your Site under compatibility view settings to resolve this issue.
- Open your Site in Internet Explorer
- Go to “Tools” Menu >> Click on “Compatibility View Settings” menu item
- Add your site to the list!
That’s all. Now the browser enabled InfoPath form should render without any issue.
