Security Token Missing for posts with big uploads

[Abhik]

Hello,
I am getting security token missing for big uploads of attachments.
Your submission could not be processed because a security token was missing.

If this occurred unexpectedly, please inform the administrator and describe the action you performed before you received this error.

I was uploading a file of 8.1MB.
My PHP Max Post Size is 12.00 MB and PHP Maximum Upload Size is 12.00 MB

Any idea how can I fix that?

The default behavior of vb does not have a issue with "big" uploads, this is a issue related to a hack you installed.
