Version 2.1.9 is broken please update to version 2.1.10:
Simple Currency Converter Add-on automatically converts prices (US Dollar, Euro, British Pound and Russian Ruble) to selected currency on every web page.
Foreign currency rates provided by Exchange Rates UK.
Quote from official website:
Here at Exchange Rates UK, we have just started to switch to using multiple inter bank rate sources, as opposed to the original European Central Bank source. This means we can offer live rates that are correct within 5 mins as opposed to a single daily rate!
Our new currency calculator can be seen to the right of this text, called Currency Calculator LIVE. It's fast and up-to-date and tells you the time/date of the latest source!
Please note, these values are only to be used as a guide and are not actual buyable rates.
