[galaxy-user] Galaxy Help!!

I am trying to use LEfSe but keep getting the same error. My data loads fine, but then I cannot get results from 'Plot LEfSe Results'. I then try to report the error, but it consistently tells me 'Mail is not configured for this Galaxy instance". So I don't think my error reports are working.
