The edit_post_link() function does not seem to work when the 'Blog address' and the 'WordPress address' for your blog are on different domain/subdomains, i.e. one has a www prefix while the other one doesn't.
The "edit post" link appears if I set both to have the www prefix or if I omit it in both. But if I include the prefix in one, but not the other, the link doesn't appear when I am logged in.
Does anyone know if there is a workaround?
Also, does anybody know how to get this link working with different subdomains, i.e. the "WordPress address" would ideally be using a "manage" subdomain while the "Blog address" will be using the normal "www" subdomain. ... That is, if it is a separate issue from the above.
