I would like to use a custom font in a web application. When trying to upload it as a file resource (using the console), I'm receiving an error message "Downloaded file 'xxx.ttf' is not authorized". I'm able to upload any other type of file. !
The server config does not restrict the upload to any file type.
Moreover, if you don't need to upload manually through the AC resources file manager, you can declare the font in your css file of your webApp, and it will be automatically uploaded (but renamed with MD5 hash name).
Last solution, you can upload directly to the server if you have access to it, put it in res folder.
