When you activate the plugin’s debug mode, it will verbosely record more information than the usual errors-only logging mode. You should only enable it for troubleshooting the plugin or when asked to do so by the support team.
When in debug mode, the plugin will continiously store the last 1.000 log lines in the WordPress database. To view the log, you can navigate to Debug tab of the plugin’s configuration wizard. To copy the log file to your clipboard e.g. to send it to the support team you can click the Copy debug log to clipboard button. Use Ctrl+V or “Paste” from the context menu to paste the debug log from the clipboard into an editor of your choice.
Simply check the option and watch the latest debug log entries being added to the end of the debug log on the debug tab of the plugin’s configuration wizard..
