In rare cases, Piwik will show “no data” for a subset of data, for example for one day, one week or one month, while other periods will work fine and report all data as expected.
How to solve this problem?
- Firstly, if you are not using the latest Piwik, please update Piwik to the latest version.
- Next, we will re-process the missing data. Please follow instructions in the FAQ How do I re-process my reports from the original raw logs?.
- Lastly, this is optional but we do recommend to setup auto archiving for your reports.
Congratulations! you should have now restored the missing data and likely prevented this issue from occurring in the future.
