I have a dataobject, administered by the great ModelAdmin, that scaffolds the

$static $has_one = array('MyImage' => 'Image');

this fives a very nice ajaxy upload and see the image, but when the image is larger than the file...

; Maximum allowed size for uploaded files.
upload_max_filesize = 2M

then I get the message "SecurityID doesn't match, possible CSRF attack." after I select the too large image from my computer and select 'attach image'...

I would be very grateful for any help one this please.


p.s. I should mention this is on 2.4.0

I got the same error when uploading large files (videos) to a site I was working on. I had to modify the php.ini file used by the server; specifically, the post_max_size, upload_max_filesize and memory_limit variables. I adjusted them to values that would fit the files I was uploading.
