Friend, thank you for responding. Could you tell me where I change this file? I'm starting to mess with xmpp now and still feel little of the difficulty in some things.
If you can tell me the step by step would be of great help.
I downloaded the file https://dev.gajim.org/gajim/python-nbxmpp/repository/c228396b3c64360dead579df269057b424a669c4/archive.tar.gz and installed with: python setup.py install I restarted the service but still with the same error as before. Is the procedure right? Can you help me one more time? Thank you.
I uninstalled the previous version and installed it: Use Gajim-0.16.9-2018-01-14.exe as requested, however the error sending files smaller than 10MB continues. I rebooted the gajim machine and the server and the error persists.
