Lefse problem with plotting

Trying to analyze my own data on Lefse on Galaxy and getting error on the third step, in term during plotting Lefse results. Could someone help me to manage this error: The image “http://huttenhower.sph.harvard.edu/galaxy/datasets/c28c6c5c4a8fe23c/display/?preview=True” cannot be displayed because it contain errors.
No differentially abundant features found in /export/galaxy-central/database/files/004/274/dataset_4274058.dat
Thanks. Attaching my input file.
