I have a couple of multisites running single sub sites at the moment and just did the upgrade to 3.8
Everything goes fine until the database upgrade phase when I get this message: Warning! Problem updating http://www.(maindomain).co.uk/(subsite). Your server may not be able to connect to sites running on it. Error message: couldn’t connect to host
Site front ends appear to be working correctly but I still have a link to Upgrade Network in my control panel and when I try and use it I get the same error message as above.
This has happened on two multisites now. Is it a glitch?
