Brief
We have modified the 'admin_currencysource.php' file after release 3.4.2 has been issued.
Description.
When attempting to update currency from currencysource.com site you received the following error:
Can't find rates to the following currencies
The reason was that Currencysource site has updated their urls for currencies feeds.
Solution.
We would recommend to download an updated version of the files from here:

Further, extract the above mentioned files into the 'admin' folder of your shop replacing an existing one. Don't forget to make a backup copy of the current file in case something goes wrong.
