The total contributions, the longest streak and maybe even the current streak counter are not working anymore. All of them have the value of zero (at the moment of taking the screenshot, the value for the current streak counter is correctly zero, but as the other two counters are not working, there might be a chance, that this counter is also not working anymore).
Please take a look yourself at the example page: https://bloggify.github.io/github-calendar/example/
