I have made a few custom pages that need form data passed from the previous custom page page via the POST method. The problem is as soon as the 2nd custom page loads up, the categories (and a few more) boxes dissappears.
do the custom pages have all the include files that the normal pages have?
Yes, it had all the include files that normal pages had. I had actually solved this problem yesterday by using GET instead of post since one of the first include files move all get (and post) variables into the globals.
But for the record, try creating a custom page with a form that passes data via the POST method into another custom page. You’ll see that it screws up some session/cookie/post variable data.
