I have a problem on my Drupal website since 2 days. When I try to add a new image (50 KB), the thumbnail is not displayed after transferring the image so I have to save the element and open it again to see the cropping box. I checked the ajax response and I found this error:
An unrecoverable error occurred. The uploaded file likely exceeded the maximum file size (64 MB) that this server supports.
I did some search on Drupal forums and SE, tried all the solutions but still have the same issue. This is my current configuration:
post_max_size = 64 MB
upload_max_filesize = 64MB
I'm not using the nginx progress module
Please note that I have another copy of the website used for development and hosted in the same server with the same nginx and php settings. This copy works perfectly.
Any suggestion on what to do to fix this issue?
