I'm trying to upload a .flv file using the Files & Images function of the backend. I did upload images and flash files before, without any problems. The .flv is 9.55 MB in size and my max_filesize in the php.ini is 10 MB.
When I try to upload, it takes some time and then the error message "Fatal error: Method name must be a string in /kunden/.../silverstripe/sapphire/forms/Form.php" appears, whereas "/kunden/.../silverstripe/" my personal path to my system is.
Germaniac - you can also upload via FTP then when you load the admin it will create the new file objects for you. When we are dealing with large files FTP then loading the assets section is the best way to go.
