some thumbnails broken

[stufraser1]

In some layers, the thumbnail does not load, but when on the layer page, the map does show, suggesting it is not an issue with the legend. e.g https://www.geonode-gfdrrlab.org/search/?title__icontains=CY-GLO&limit=20&offset=0

For reference, query to fix that in the DB:

UPDATE base_resourcebase
SET thumbnail_url=replace(thumbnail_url, 'https://www.geonode-gfdrrlab.org/media/thumbs/',
    'https://www.geonode-gfdrrlab.org/uploaded/thumbs/')
WHERE thumbnail_url LIKE 'https://www.geonode-gfdrrlab.org/media/thumbs/%';
