<p>Hi Francesco...<br>
</p>
Bingo!!!<br>
Thank you<br>
<br>
Testing the countries of Natural earth I have seen that the thumbs
was created. So I decided to try again with my data..<br>
<br>
it seems that, in order to generate the thumbnails the layers must
be in epsg:4326 !!!!! This is true for vector and raster data
(shapefiles and tiff at least).<br>
In precedence I have tested only with data in epsg:32633 (UTM/WGS84,
zone 33) and other CRS but now I see that WGS84 lat/long is the only
CRS in which Geonode is able to generate the thumbs..<br>
It is not perfect since we have to re-project the data and that can
generate some problems (re-interpolation algorithms for raster,
datum transformation errors), however it is good enough for
starting...<br>
<br>
do you think it is a bug or a well known feature? <br>
do you think it can be solved?<br>
<br>
thank you again<br>
Ivan<br>

Ivan,

</div>
<div>given your answers then, assuming your are testing with the
same datasets ever, can you try with different data? Maybe
classic shapefile like countries from natural earth.</div>

<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>

<div class="">what else you can do is check the

<br>
Yes, thank you.<br>
The files exist but they are white png images<br>

<br>
yes... the thumb file is there:
