We are using multisite to host 30-40 wordpress sites, as well as many individual installs of wordpress and are experiencing the 'noindex' option turning itself on/off. It is happening to sites that have been untouched for months, new installs, on versions of wp3.1.3 - 3.2. Devellpment sites set to noindex are being switched to index, and sites that are indexed are being turned off. There is no consistency to which sites are turning, and when they turn.
Has anyone seen this before?
If so, do you have any direction to look towards troubleshooting this issue or a possible solution.
