Could you give me a specific URL that you're seeing this behavior on? Could you let me know the settings for you've customized the SCSocialWidget module for this Twitter widget? Usually this error is caused by the options being set incorrectly.
Please provide me with the full URL of the "URL / Status ID" setting. It is cut off in the screenshot and not showing in the browser's debug tools. This is usually the culprit and must be a valid link to a Twitter Post, so I'd like to test with the actual value that you're using.
