CMC integration is now working again in version
5.0.3 of the plugin.
You are now required to enter an API key, which can be obtained for free from CMC. Previously, the API key was optional.
If you have enabled any fiat currencies using the Fiat Coin Adapter Extension, then you should also enable the fixer.io service via an API key. This helps the plugin know which currencies are considered fiat, so that it does not attempt to query the CMC server about them.
Thanks again for letting me know about this issue.
