goaccess statistic report for monthly has no data

Do you have a solution to fix the issues in goaccess statistic report for monthly has no data?
This was encountered for all the domains.

I can confirm that on all 3 of my CWP servers, the monthly directories are empty. (I have daily and weekly entries aplenty.) So that would imply it is a default configuration that needs to be changed. I haven't looked into it, because it's not something of critical importance to me nor the end users on the server.

I had this problem to and then i enabled logrotation on a weekly basis and that made the monthly stats start to work again. The log files were too big for goaccess to read.
