<br>
thank you for the hints<br>
I have cleaned the browser cache but the problem is still there: the
thumbnails exist but they are png images completely white<br>
The thumbs dir has the following rules<br>
<br>
ls -al /var/www/geonode/uploaded/<br>
<br>
drwxrwxrwx 4 www-data www-data 4096 nov 24 13:51 .<br>
drwxr-xr-x 5 www-data root 4096 nov 24 13:50 ..<br>
drwxrwxrwx 2 www-data www-data 4096 nov 25 19:20 layers<br>
drwxrwxrwx 2 www-data www-data 4096 nov 26 15:08 thumbs<br>
<br>
I think they are fine...<br>
<br>
Moreover I have tested that the thumbnails of the maps are correctly
created and, if I'm not wrong, they are stored in the same folder of
the layers thumbs <br>

<blockquote type="cite" cite="mid:A2B6ED4D-53BB-49E3-A1C3-949BD4C9A2C4@csgis.de"><br>
<div class="">what else you can do is check the thumbnail url and
see if the image exists on your</div>
<div class="">drive.</div>
</blockquote>
<br>
Yes, thank you.<br>
The files exist but they are white png images<br>
<br>
<blockquote type="cite" cite="mid:A2B6ED4D-53BB-49E3-A1C3-949BD4C9A2C4@csgis.de">
<div class="">An easy way is as already suggested to use the
browser console. Or to navigate</div>
<div class="">to a layer in django admin: <a href="http://yoururl/admin/layers/layer/1/" class="" moz-do-not-send="true">http://YOURURL/admin/layers/layer/1/</a></div>
</blockquote>
<br>
yes... the thumb file is there:
uploaded/thumbs/layer-40a378c6-d20d-11e7-a6fc-0050568d40c1-thumb.png
<br>
<br>
<br>
thank you again...<br>
any idea or strategy for understanding the problem is welcome<br>
<br>
best regards<br>
