A couple of notes here.
- You should not be modifying the files directly, your changes will be overwritten with every Discourse update.
- You’re on the Bitnami install which we don’t provide support for here.
- I’m not sure what’s available to you on the Bitnami install, but this is how you would do it on the official install
Add long site description to about page - #5
If you need more support, please make sure you follow the official installation guide here first.
