I have created a form where it is possible to write posts from the frontend. The category dropdown does not work. It does not save for some reason.
It can be seen and tested here: http://naturoghelsebornholm.dk.linux43.unoeuro-server.com/min-konto/mine-blog-indlaeg/opret-rediger-blog-indlaeg/?postid=59
Normaly this page is for logged in users only, but I have removed that restriction for now, so you can test it.
I hope someone might help me.
