Issue Webalizer showing statistics for the 2 most recent months only

[Lutuh]

Hello there,

we have encountered an issue with web statistics provided by webalizer, where only the two most recent months are showing up on the statistics page and the corresponding webalizer.hist file is filled with zero-values except for the most recent months. All the other entries exclusively contain zero-values. Even after rebuilding the statistics (see: Website statistics (Webalizer) does not show relevant data ) the issue persists.

But there are in fact html pages with proper data for the value-less months as we were able to "repair" the statistics with a script that crawls through those files and aggregates the missing statistics, which then can be pasted into the hist-file.

We run Plesk Onyx on our Ubuntu 14-04 servers which includes Webalizer V2.23-08. Does anyone know the issue or has a solution?

We can provide more info if needed.
