Missing styles & js when opened over https

When open [https://ivanvergiliev.github.io/](https://ivanvergiliev.github.io/)
```
[blocked] The page at 'https://ivanvergiliev.github.io/' was loaded over HTTPS, but ran insecure content from ***: this content should also be loaded over HTTPS.
```

I think, the protocol is not explicitly used anywhere so it should work (just updated my blog's config as well, although I don't use HTTPS).
