Okay I see the issue. My apologies - I didn’t know how much had changed in the social sections between the last Minima release 2.5.1 and the files on master which I had linked you to.
You had copied from the latest minima which expects social links like this:
You misunderstood how social.github was read. The social reference was just a reference to minima.social-links at social.html on master.
The approach you need to use in your config for Minima 2.5.1 is like this config.
e.g.
github_username: abc
orcid: 123
I’ve made a PR to fix your config, social.html file and delete footer.html
