Tried that as well.

I found that it has to do with the CSRF protection being defined to true on PAGE B. I tried sending the hash and security token in the form as hidden with:

<input type="hidden" name="s" value="$session[sessionhash]" />
<input type="hidden" name="securitytoken" value="$bbuserinfo[securitytoken]" />

And that did not help. I am at a loss.

--------------- Added [DATE]1334041500[/DATE] at [TIME]1334041500[/TIME] ---------------

Sigh, its getting late and I am just not thinking things through.

I forgot to alter the values for the change in how vb4 handles the variables.

<input type="hidden" name="s" value="{vb:raw session.sessionhash}" />
<input type="hidden" name="securitytoken" value="{vb:raw bbuserinfo.securitytoken}" />

Fixes the issue.
