Hi,
I am experiencing exactly the same issue as in this thread : viewtopic.php?f=52&t=10312&p=47793&hili ... ils#p47793
I don't have several servers/instances/websites using it, only one.
however, my file name is "DANSE.jpg"... and contains no special characters.
I have a particular setup in regards to PHP, and I wonder if it could be due to some missing extensions ?
However, if I go to ?diagnostics, GD extension is correctly detected.
Mysqli and Exif are off, but I don't think it will lead to such issue.
Therefore I wonder what could be the cause...
If I look at "inspect element" on the faulty thumbnail, Console gives me error 500, and opening in new tab (the thumbnail, not the link to the big image, i.e. https://mywebsite/render/w100-c1.1/peinture/DANSE.jpg) gives me an error :
"Error
Failed to call imagecreatefromjpeg()
<?php array (
...
"
and then I have some PHP code...
Could you let me know what other details you need to assist me please ?
Thanks !
