SSH Problem? Editing .xml

Hi All, I just upgraded to the EX2100 and have been trying to do what I did on my old 4tb mycloud which is to edit the xml file for panasonic tvs just to change the sort order (I posted a thread a few months ago explaining how I usually do this). However on the new EX2100 whenever I try to either edit or replace the xml file it says there is an error. I even tried installing cyberduck and I cannot seem to get it to work with that either. Is there less permissions with the new EX range or is there something else I need to do first?
I posted this in another thread as well but thought I’d put it here in case anyone else is having an issue.
Thanks in advance


I have not tried this, lets see if another user can share some information or tips on this matter.
