i'm working with a WordPress site developed by someone else , when i login to dashboard and try to edit any custom post type that takes me to blank page for example there is a post type news and when i press edit button against any news item this is url
site.com/wp-admin/post.php?post=795&action=edit
And there is a blank page under it , i can edit posts and pages but not custom post types , this site is done by some one else so really don't know about problem can someone help me normally why blank page comes in WordPress while editing something. if i do quick edit that is also available and change can be made through that ,
And one more thing if i want to change values of CPT from phpmyadmin (db)directly in which table should i look for custom post types
