Error :
Error "ImproperlyConfigured at / 'PageAdmin.exclude' refers to field 'created_by' that is missing from the form" Problem Solve : Fixed this error by just setting editable=False on created_by and changed_by and removing all fields from
PageAdmin.exclude (the other fields already were editable=False) Edit two files to fix this error
Edit file: cms/admin/pageadmin.py Line no. 65 approximately. revision_form_template = "admin/cms/page/revision_form.html" Change this line - exclude = ['created_by', 'changed_by', 'lft', 'rght',
'tree_id', 'level'] by + exclude = []
mandatory_placeholders = ('title', 'slug', 'parent', 'site',
'meta_description', 'meta_keywords', 'page_title', 'menu_title')
top_fields = [] general_fields = ['title', 'slug', ('published', 'in_navigation')]
