In the event where you need to troubleshoot the scanning done on a specific target, you can enable debug logging for the Target. The Acunetix scanner will log the progress of the scan and any problems that are encountered during the scan.
You can enable debug logging for a Target by browsing to the Target’s settings > Advanced tab, and enabling “Debug scans for this target”.
The debug logs are stored in <C:\ProgramData\Acunetix 11\shared\scans>. The Events tab of a scan will indicate the name of the zip containing the logging for the scan.
