In this topic I made you should see the emoji image doesn't load. That's because it's trying to load from http://unblocked.gggrealms.ml/plugins/nodebb-plugin-emoji/emoji/customizations/ea9804b2-6c62-4ca1-b8b4-0d79bd12eb10-touchicon-orig.png which I think the browser blocks.
It's loading from there because that's your url in config.json
