Invalid security token error

[MarkFL]

What I suggest first is to do a search in your templates for:

{vb:raw userinfo.securitytoken}

And change any instances you find to:

{vb:raw bbuserinfo.securitytoken}

(Make a note of all templates changed in case you need to revert).

Then, check the links in your "Navigation Manager" for instances of:

{userinfo.securitytoken}

and change those to:

{bbuserinfo.securitytoken}
