HI @Jose Palacios
The error message you receive "The item could not be uploaded. Please refresh the page" usually indicates a problem with the upload. We recommend that you try refreshing the page, but simply refreshing the page may not resolve the issue.
Here are some troubleshooting steps you can try:
Clear your browser cache: Sometimes, data in your browser cache can interfere with the upload process. Clearing your browser cache can help with this type of issue. After clearing the cache, try uploading the dashboard again.
Try a different browser: Switching to a different browser can determine if the problem is specific to the browser you are currently using. Try using a different browser and see if you are able to upload the dashboard without errors.
Check file size and format: Make sure the dashboard file you're trying to upload meets the platform's requirements. Check file size and format restrictions and make sure your file meets these requirements.
Verify internet connection: A stable internet connection is essential for uploading files. Check that your internet connection is stable and there are no issues.
By following these steps, I hope this will help you troubleshoot the "Failed to upload this item. Please refresh the page" error and successfully upload the new version of the dashboard you added earlier.
