The scanning profile editor is unable to save any changes made in the HTTP/FTP timeout setting under Network & Software Audit Options > Applications > Advanced Options. The editor appears to have saved the changes but when you close the scanning profile editor and open it again, the value in the HTTP/FTP timeout setting goes back to 60, which is the default value.
Upon checking the debug logs, there are no records about the changes made; only the following entries are recorded.
