This is a question sent to the Customer Support team recently:
In the Administration panel, when I try to open the last report for a WP / CP, the interface displays logs from 6 days ago instead of the new one from today.
The reason you have only the date of 6 days ago in the AWI display is that your log files are not triggered to rotate every day. If you go at the end of the last report, you'll find some execution from today while the logging started 6 days ago.
You should check values of CHANGE_LOGGING_DAYS and CHANGE_LOGGING_MB in the variable UC_SYSTEM_SETTINGS. The variable can be found in the Process Assembly of your client 0. If you want one file per day, please change the value of variables CHANGE_LOGGING_DAYS to 1.
