To some extent it is possible to specify custom error/success pages within GuestPost. I don´t use GuestPost myself so I can´t be more specific then that.
But I also know that it is a problem using guestpost and other addons which may present there own errorpages (overriding the error/success page setting within GP). Multipart and CustomFields are examples of such addons, but it really isn´t there fault, currently it just is no other way for them to handle errors. This has been discussed before in
this thread, including a solution. It is not possible without a change to both the core *and* the addons presenting the error messages though. Maybe this could be attended within the 1.30.x series, making mental note...
