What is a "poller"?  Do you mean the overall rank / 7 days rank?

All seems good here so far and no other reports of this issue.
Did you cash out your balance by any chance?

If you're waiting on a payout from fotolia it's possible they've just processed it (and so reset the credits amount in the left sidepanel to zero), sometimes there is a lag between them updating the database and actually sending the payment (it's been a few months since I cashed out there though so can't be certain).

If it's not reflecting new sales and/or you don't get a payout from fotolia in the next couple of days, (and you have checked for updates using the firefox addons panel), then please drop me an email on [email protected] and I'll get back to you with some questions to find out more about your specific setup

Noticed a very rare bug here (it's actually the fotolia website), it seems they occasionally output the balance as "#." ie. with the decimal point on the end but with no value after it. I'm guessing they have a wrong output specifier for a php sprintf call (or something similar). I'm guessing it's something to do with the small fractions of a cent sometimes earned by their referral programme.
Have updated the poller spec to account for it, and it shouldn't be a problem anymore
