Your submission could not be processed because a security token was missing

[tmi]

I try to create an external website that used vbulletin user account.
I only include "login.php" file into all my script.

But some problem occured while submitting form, it says "Your submission could not be processed because a security token was missing."

Is there any workaround for this?

Thanks in advance.

Have you added vB Code correctly?
