Debug logging is not enabled for "Customer & Business Manager" by default.
If an error occurs, the debug logging helps you collect the information necessary for our support engineers to diagnose and fix it. You should turn this service on, reproduce the error, and attach the newly added log records to the error description.
To turn on the debug logging, do the following:
1.In the file
config.php, set "true" for the parameter
If you run Linux, the file resides in
If you run Windows, the file resides in the directory
2.Go to Server Administration Panel -> All Settings -> Debug Log and click Enable Logging in the opened page.
This information can be found in Parallels Customer and Business Manager Administrator's Guide and also at the Parallels Plesk documentation page.
