How to add a new currency to admin, site settings

Problem:

There are only USD, GBP and EUR listed as an available currency within the site settings. You need to add another currency.

Fix:

In the database look for site_config. Find 'cost_currency_code' record. Replace 'availableValues' with your own currency code, i.e:

["USD", "GBP", "EUR", "INR"]

Also find 'cost_currency_symbol' and do the same:

["$", "£", "€", "₹"]
