From here you will want to select the Log option in the left sidebar.
By default the log will have the four types of messages enabled. To disable a specific type, click it. The above below has Log displaying while Info, Warnings and Errors have all been hidden.
This is especially useful when testing and debugging with d=1. A disabled command will appear under the Log filter and the information related to that command would be found under the Info filter.
If you encounter something in your log and are unsure as to what it means, please feel free to contact us at firstname.lastname@example.org. Providing a screenshot of your log will help us with debugging your issue.
