I have a domain that was running 3.05 fine. Links and images were working. Blog seems normal and healthy.
As background, the site is on Windows IIS 6.0.
one evening, I started to enable Network, specifically, enabling the sub-directory model.
I came back a few days later, finding that it did not appear to be enabled, so at that time I enabled sub-domains.
I imported a "wordpress.com" site and everything looked fine, except there were no post images and links were broken.
Primary domain still had no problems.
Today, after applying the latest updates, i returned to the sub-domain to see what was wrong.
In the Network admin I noticed that I had a sub-domain site and a sub-directory site of the "sub.domain.com" and "domain.com/sub/"
The sub-domain site is working, but links required that I put "/index.asp?/"
between "sub.domain.com/" and the "/postname/". Images also do not work on that site.
On the parent site "domain.com" the links were not working as well. Both were originally setup to use permalinks in the custom format of "/%category%/%postname%/".
I just changed both back to default and the links work in both, but the images do not in "sub.domain.com"
Does this spark any ideas?
