Upgraded to latest development branch and ran composer install. Things seem to be working except on the cli interface:

Look like you don't have enough right to /var/log/ampache/ , add write access, try again and send us the log of the ampache.log file

cb7aa3e removed the get_m3u_string which is used in

ampache/src/Module/Playlist/PlaylistExporter.php

Line 126 in fc9325a

$plstr = $pl->{'get_' . $ext . '_string'}();

and because the function name is generated, it was not in the alert

[fufroma]

temporary fix, add in the src/Module/Playback/Stream_Playlist.php

    public function get_m3u_string(): string {
       return $this->create_m3u();
    }

EDIT : not a good fix, it print the M3U in the stdout instead of creating M3U files. Need more time, don't have right now :)

does the job but may have unexpected problem:

Sorry for the noob question but is there an easy way to apply a patch via git or should I wait for this to be committed?

Not related to this issue, this is an upgrade issue (which can be expected on develop branch). This could go on a dedicated issue :)
