I have a page in Facebook for a website I own. I am the admin for the page, but I am unable to change the page info, picture, etc. How do I enable those options? If I am unable to restore these options, is it possible to delete the page (has custom vanity url) and then create a new page with the same custom vanity url?
This is what the Edit Page looks like:

As you can see, the following sections are missing from the edit page:
- Your Settings
- Basic Information
- Profile Picture
- Featured
