Uploading a file on wiki.informazioni.wiki, it appears this message: "Errore nella creazione della miniatura: File con dimensioni maggiori di 12,5 MP". Help!
Just a question: when was the last time you tried?
Now you can upload up to 51 MB anyway:
Now there is this set into your Apache configuration file:
php_admin_value post_max_size 51M php_admin_value upload_max_filesize 51M
When I tried to re-upload a file, I couldn't see the image. I think the problem was not related to the size (expressed in MB), but to the resolution – or whatever it is – (expressed in MP).
