Issue with custom meta boxes.
I'm having a wierd issue with my custom meta boxes. They appear correctly on posts and on custom page templates. But, on the default page template they will load when you create a new page. After you hit publish or save the meta boxes dissappear.
This is the Meta Class
This is how i am calling the meta boxes:
If i switch the $meta_posttype to post or leave it as page and set the $meta_template it works fine. Please help I am totally stumped.
