This isnât a question, but rather a âsolutionâ that I am posting in case others fall into a similar scenario.
I had thought my Embedded Timeline wasnât working, as it was only displaying the âTweets by @usernameâ text line, and the Chrome Javascript console revealed that the widget.js resource was failing to load.
I then checked in Safari to see if the same issue existed, but to my surprise, the timeline displayed perfectly.
The answer is that I had enabled the âDo Not Track Meâ extension in Chrome, which was preventing me from loading the external widget.js resource. Disabling the extension on my domain in Chrome revealed that the widget was actually displaying perfectly.
Not sure if anyone else will ever have a similar problem, but again, just wanted to record this in case they do.
