@SharedGrid you might be right...that options is disabled on the package level.
On a side note, yes, I was accessing on the customer level. Enhance always impersonate customer if you click any of the website, which is not so good, I think? Why not access the customer package/website settings with admin level, where you can restore the website, do manual backup etc, but those options have disabled for customer? This is very ilogical to me.
