I wanted to re-arange a newly added widget to my dashboard and I noticed the position doesn't get saved. I fired up the console and when dropping the widget after dragging, I see the following error coming up:
TypeError: $widget.dashboardWidget is not a function index.php:3136:9
I figured this would be the cause. Running version 3.11.0.
I can't reproduce this here. Any chance you can reproduce this on our demo? https://demo.matomo.org/index.php
Do you know if you're using any third party plugins?
I can reproduce it on that demo as well, by adding a widget. I added User Comments (a Goal). Then I dragged that widget to another position.
