WordPress can output debug information to a file called debug.log. However, for this to occur, certain flags need to be set in the WordPress wp-config.php file. We have a one-click option to turn these flags on as follows:
After a while the screen will refresh – if the operation is successful. If the operation fails, you’ll get a popup message.
You can see a full log of the operation under the SSH LOG screen.
To disable the flags:
Do not manually delete the debug.log file from the wp-content folder unless you are ready to turn off the debug flags. Once the file is deleted, the permissions set for the file will NOT allow WordPress to re-create the file. Instead, you will need to turn off the flags and turn them back on (which will create a new blank file that WordPress can write to).
