When I click the "update" button on the home page, this is a error log in console, as shown.

Could you provide the cachegrind.out.* file you are trying to load?

What web browser, version, and OS are you using?

I think this has nothing to do with the cachegrind.out.* file, because I find the file does not exist in the directory tmp.

Looks like it is a known bug. I will look into when I have some time.

Also, pull requests always welcome.
