When I click between each tab in System -> Server Config then red circle shows at the top and after each click the number is higher. When I click on this circle I see message "datalog_status_u_server: ". What does it mean? I have 6 inside circle and this same value is shown as parameter of mentioned message. PS In which tab I could find "A log retention option has been added to System > Server config which allows it to configure how long the following ISPConfig log files are kept: ispconfig.log, cron.log, and auth.log."
