Log files can be very useful for the support team to investigate the cause of an issue.
You can export the log files from the System Settings.
At the top right, navigate to Global > Troubleshoot.
Select the download-logs action and pick the appropriate time period (mind: these dates are in UTC, which is likely not your time zone!).
Click [Execute] to generate the logs.
Leave Json output set to disabled unless told otherwise.
You will get a message that the logs are being exported. This may take some time.
If you click the download link, you can download the logs as a ZIP file.
