Hi, I am working to make new theme. I have a problem when I create/update post, category, post type, etc. I have blank page. It stop at http://www.example.com/wp-admin/post.php and showing blank page.
I know the problem is function.php. When I deleted all code, any create or update at wp-admin is work. When I get back the code, is broken again.
In my localhost, my theme is totally work.
Any suggest? I hope the problem is with my server host.
