Thanks for the response. When I import a category XLS file with unique category and sub-category names, this is the error I get. I have to restart the application each time I want to import categories because if I don't, it does not load as many categories as it does when the site is restarted. if I import a 2nd, 3rd, and 4th time, all the categories eventually import but then I am not able to import products because I get an error that I have duplicate categories. I would like to keep the same name under different parent categories but it seems I am unable to do so. for example, I would like to have "Storage" under Classrooms and Media.
