No logs for two days

Hi Everyone

I am new to Piwik so this could be a really simple thing but here goes…

I have installed Piwik, using the Moodle local plugin, but for last Friday/Sat and Sunday there are no results for user visits etc. showing up. There are visits on the surrounding days, but we know people were using the, both as registered users and also guests.

Any ideas?

Thanks in advance
