I have the same issue. I just installed a clean install of 3.2.1 and the “Networks for WordPress Plugin”. I get these two errors on the main site only.
Site 1 has an invalid meta value in home. This may prevent access to this site or disable some features.
Site 1 has an invalid meta value in siteurl. This may prevent access to this site or disable some features.
Note, I setup the main site to use subdirectories for multi-sites. Does this make a difference? Can someone smarter advise on this issue? I can’t figure this one out.
Thanks!
