Blur() not working

I’m using blur(), it’s working on local but not online…I’m using Kirby Is it a bug ?

this is the image I get with blur()
$image->thumb(['quality' => 100, 'blur' => 30, 'width' => 1920,])->url()

Which thumb driver are you using? Are other thumbs created correctly on the remote server (make sure to test this without copying the media folder from local to remote).

If it works locally, it is rather something server related.

optionally you can use CSS only as a workaround, e.g.:

.thumb {
  filter: blur(4px);
