If one of your domains shows a click but zero revenue for a single day, please make sure that stats for this day have been fully updated. This is the case only if the respective date is not marked by an asterisk on the dashboard.

If the respective day has been fully updated and still shows a click but no revenue, the explanation is pretty simple:

Our system counted a click on one of the ads and the stats therefore show a click. Our upstream feed provider however either counted the click as invalid or didn't count a click at all and did not credit us any revenues for that domain for that day. Thus, the domain shows a click but zero revenue.
