Now it seems like you are not visiting https://wehindi.com but http://wehindi.com
I would suggest adding automatic redirect to https:// trough your ,htaccess file, or appropriate place before going live with the site.
Edit: It redirects me automatically already
Edit 2: Does the same happen if you use this link: https://wehindi.com?
Also, I can now register on the site, so the change you made worked. Earlier, it crashed when I tried to make an account ( flarum.js tried to contact an non https source). Now it works:
