Sigasi HDT logs all internal errors to a log file. You can find this file in: workspace-sigasi/.metadata/.log This file is also reachable in Sigasi HDT itself via Help > Open log. The log file contains no sensitive information about your organization. On some occasions, the Sigasi Team may suggest to send them the log file to debug or improve the product. However, the option to do so or not remains yours. Instead of posting the log file on the forum, you can send it to support@sigasi.com
