Ok. I can’t see from the screenshot where is that coming from exactly. Can you make a wider screenshot and perhaps clicking on that error? I’m unable to reproduce this on any of my test installs.
On the other hand this is just a client side javascript error, it should not affect the statistics page (it’s not using the .sortable(), which causes the error), but I guess that the plots are not viewing because of this.
Also, if you cold provide temporary admin/ftp access it would help me a lot to locate the source of this as I can’t reproduce the issue unfortunately.
