Troubleshooting Internet Explorer Issues
This section covers common issues you may encounter with Internet Explorer and recommended resolutions.

Issue:
When opening the K2 Designer or trying to edit your SmartForms, you may encounter the infinite spinner. Confirm this is the issue by pressing F12 to open the developer tools window and check the Console output for the 'XPathResult' is undefined script error.
Resolution:
To resolve the issue follow these steps:
- Open Internet Options
- Select the Security tab and Internet zone
- Click the Custom Level ... button in the Security level for this zone section
- Scroll down to the ActiveX section and enable the Run ActiveX controls and plug-ins and Script ActiveX controls marked safe for scripting settings:
- Reload the K2 Designer

Issue:
Certain legacy K2 components, like the K2 Designer for SharePoint and the Notification Designer, require the Internet Explorer Enhanced Security Configuration (IE ESC) to be disabled. The IE ESC restricts rendering the interactive javascript used by the AJAX controls used to give users a Windows-like feel in the designers. This is a known issue and will be fixed in a future update.
Resolution:
- Open Add/Remove Programs by clicking Start > Control Panel > Add or Remove Programs.
- Click Add/Remove Windows Components.
- In the Windows Components dialog, scroll down until you see the Internet Explorer Enhanced Security Configuration component.
- Uncheck the checkbox next to the Internet Explorer Enhanced Security Configuration item.
- Click Next, and the wizard will configure the components.
- Once the configuration has been completed, click Finish. You can close the Add or Remove Programs window.
