Asterisk Gui: music on hold don't go

Hi
i have a problem with music on hold because i try to upload from the page in asterisk gui but it not upload file.
So i upload music direct from shell or with an ftp software.

If i try to call my number i see this message on the cli:

I don’t undestand why asterisk don’t see file jubel_mono_2 and i don’t undestand other 2 warnings
Directory and file have asterisk group and asterisk owner.

Someone can help me?
