Widget broken after site switched to https
Two separate problems with the same source, which is that your widget is static HTML and Javascript that you copied and pasted in place.  It does not update by itself when you make changes.

If you just see the placeholder text, it means that the Javascript is failing to get the current totals.


Your widget may be trying to connect to your site, failing because it's not connecting through HTTPS.  Depending upon how you implemented HTTPS, these sorts of connections may fail unless you specify the https://... URL.
Your browser may be refusing to connect via an insecure protocol.  Recent versions of browsers will simply exclude Javascript and CSS that comes through HTTP when you're on an HTTPS page.


The solution to either problem is the same: fix the widget.  You can read through the widget's code and replace each instance of "http://" with "https://".  Alternatively, you can simply go manage your contribution page, go to the widget tab, copy the code, and paste it in place of the old code.
