QuestionThere is no "Export template" option, what should I do? I am using the community version.Community AnswerIf the "Export template" options is unavailable, then it is likely that you failed to keep open "Project-0" when trying to export the template. It is the mother or patron project for creating the template with it. If there is no project open, you can't create a template, so there is no "Export Template" option.
