Installed this mod today on both of my stores (in separate sub domains) and simply duplicated the file currency_update.php as store1_currency_update.php and store2_currency_update.php.

Set up cron jobs as below, tested in cPanel and browser and it worked immediately without a glitch.

Great mod, thank you indeed. Shame the ECB does not update the xml file more often, especially when the markets are volatile.

This cron job has been suggested previously

/usr/lib/php /home/username/public_html/path/currency_update.php
My host requires

/usr/local/bin/php /home/YOUR_USER_NAME/public_html/store1_currency_update.php
and

/usr/local/bin/php /home/YOUR_USER_NAME/public_html/store2_currency_update.php
In the above command please note the space BETWEEN /usr/local/bin/php AND /home/YOUR_USER_NAME/public_html/store2_currency_update.php

if you close that gap (ie no space) the whole thing falls over.
