I have a fresh multisite installation set up on:
with 2 subdomains added to the network:
In cPanel, 2 parked domains have been configured: sub1.com and sub2.com and point to the public_html folder of the primary domain.
I have installed the WordPress MU Domain Mapping Plugin. (only option 2 is checked).
Everything appears to be working correctly except for the paths of featured images served from the mapped subdomains.
All images show up correctly in the primary domain and in the mapped subdomains.
But Featured Images in any of the mapped subdomains are being served from:
This does not happen with any images inserted into the post body. They are all correctly served from sub1.com/etc
Is this normal behaviour for Featured Images on a MU install?
