After you have downloaded the latest.log file, you can open it with a text editor (such as notepad). This is an example of a line in latest.log: [11:57:30] [Server thread/INFO]: Debug logging is disabled The first section encapsulated in [] shows the date when that line was logged. The second section explains what the log line is about. What you usually need to look at is the section after Server thread/, in this case it says INFO but in other situations it says WARN or ERROR.
