I am using Worspress Multisite feature, where I have two domains:
lkrnac.net -> main domain
handysvandy.net -> secondary domain
Not using any special plugin to handle multiple domains.
In Network Admin area I have two sites registered with two mentioned domains. Also have "Path" set to root ("/") for each site and checked "Update siteurl and home as well" check box.
Everything works generally fine. The only problem is that when image is uploaded for secondary domain (handysvandy.net), it is uploaded and served from main domain (example: http://handysvandy.net/2014/06/12/dandelion-and-parsley-salad/).
What should I do to have images served from and uploaded to secondary domain?
EDIT - source
I followed this blog to set up domains for multisite: http://kaspars.net/blog/wordpress/wordpress-multisite-without-domain-mapping
EDIT2 - example links
EDIT3 - new fact
After usage of "Velvet Blues Update URLs" plugin that replaces domain for images, images are served from correct URL. So it looks like issue during image uploading.
