Ok it’s an update. Then I’ll post you the answer of Daniel Molina (dmolina) at the IRC to the same issue, according to this forum post there have been some changes in the yaml views file, and some variables have changed from a boolean to an array… then old views would not work as expected and shows a spinning gif like yours.
Have a look at that post and use the latest yaml files at GitHub to check the differences if you want to keep your old views if you’ve made some modifications (e.g https://raw.githubusercontent.com/OpenNebula/one/master/src/sunstone/etc/sunstone-views/user.yaml) or use directly the new yaml files if you don’t mind overwrite them (always proceed with caution 
)
Cheers
