Web Map Background Troubleshooting Tips

You might experience errors when you add a web map background. For example, a web map background image isn't displayed in the Preview tab or in a visualization.

Use these methods to find and diagnose web map background errors:

• Press F12 to display the browser Developer Tools application and search for errors in the browser console tab. For example, search for error or CORS. Error messages are displayed in red text.
• If you see an error message similar to Access to image at http://example.com has been blocked by CORS policy..., contact the host provider to resolve the issue. Error messages that refer to the Cross Origin Resource Sharing (CORS) policy can only be resolved by the host provider.
