Yesterday I uploaded the new version of wordpress to all of my websites...I then went into my custom menu feature to add more topics...I tried to drop and drag my items into subgroups for my navigation bar, it will not allow me to do so....I spoke to my hosting company and they said there were no errors on their end. I've tried to reupload an older version of word press and I'm still getting the same result. I've also deactivated all of my plugins. An administrator from the Studio Press forum told me it was more than likely an issue with installation. Any suggestions to fix this? Thanks.
