Thread:Project:Support desk/Error creating thumbnail: Unable to save thumbnail to destination/reply (10)

For me this settings in LocalSettings.php worked:

$wgEnableUploads = true;

$wgUseImageMagick = false;

$wgImageMagickConvertCommand = "/usr/bin/convert";

$wgTmpDirectory = "$IP/images/temp";

and create "temp" folder in /images
