My site is using a short vanity URL. This is working across all of the custom theme pages. The only problem is when I logout in the admin it redirects to the long URL, which then 404s.
My General Settings (which I can't change) are:
WordPress address (URL): The long URL Site address (URL): The short URL
Looks like the logout link is generated from wp-includes/general-template.php, but I hate to edit core, non-theme, WordPress files.
Any ideas how to solve this logout 404 problem is greatly appreciated.
