Error when i run BOM locally

[Teog102]

I installed BOM locally on my pc as suggested in the manual and it starts just fine. When i upload files and press the get taxa button i get a message "error: 'names' attribute [2] must be the same length as the vector [1]". I tried changing the file names and even reinstalled the packages but i get the same result. Any suggestion of how can i fix that?
