We bill our subscriptions in USD but recently it was decided to accept Euros as a secondary currency. Having made the appropriate changes to CBSubs settings we were unable to get this working. Then we noticed that the currency rates had not been renewed since 30 Jun 2018. Checking back we found on that date we had updated CB to 2.2.1 and CBSubs to 4.3.0.
Can you suggest what I should be looking at to resolve this?
Please update CB and CBSubs to latest nightly builds. You can do that from Install from Web tab, after being logged in at
