Hi drmike,
Many thanks for your reply,
Just upgrading to WP 2.1.2 for example.
I’ve previously read the upgrade info and digested it. However, it appears to give an example of upgrading for just one blog, if I read it correctly. Whereas I have several blogs on one server. I do not want to have to upgrade each one individually as I think this is impractical. I guess there must be a way to do this do this upgrade without having to do each and every blog. Am I correct in assuming this is the case?
If so, do I just do the upgrade for my main blog in the root domain?
