The "No Sync" happen to me when my Vera reload or reboot.
The creation tab issue, I guess this is again a permission issue,
I would go to the root of the directory on your http server on the NAS and change the rights for all files.
full read and full write permission, in unix it is a "chmod -R 777 Myvera"
what happen when you answer yes?
I had this issue, I have answered yes, then refresh my page, showed again and answered "no", then refresh again.
after that you will have the same message for the Vues -- until you create them. at least one.
