I am getting this error on new subsites created...the error happens when going to update the network in the multisite area.
Warning! Problem updating http://testsite.mysite.com. Your server may not be able to connect to sites running on it. Error message: Couldn't resolve host 'testsite.mysite.com'
Let me know how I might fix.
I am able to browse to the site with a browser though as normal (on the surface). But, there is something under the hood not right.
