Replying to myself with more info: The problem is something to do with basic .htaccess/.htpasswd authentication. I removed the .htaccess from the folder and the image upload works fine. Replace the .htaccess and I can no longer upload.
The .htaccess file reads: AuthType Basic AuthName "Enter Valid Login Details" AuthUserFile /home/sites/<domain>/.htpasswd Require valid-user Nothing special, and it has worked up until now. A server reboot has not fixed the problem, either :/ DD _______________________________________________ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx
