Help with remote login

[misuse]

I have a custom cms in front of the /forums/. When logging in from the cms I get the error:
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.

Here is the code. I did research on it and found this code somewhere months ago. I whitelisted .domain.com in the vbulletin general options as well.

Help!
