2. Yeah, refreshing browser while you're in admin
3. check with your hostingprovider if their server-setup is OK. Server-sequirements of SS are for example a memory-limit of 32 MB (a little bit below that should also work in my experience, but not to much of course. Maybe it's possible to bypass the server-setup as suggested here.
4. If nothing works, still: check with your hostingprovider and explain them js isn't working well. Maybe they know something?
Unfortunately I don't have any further suggestions. For me: everything that worked badly on my local wamp-installation went fine as soon as I put my site online, so I'm pretty convinced it's in the server and not in SS. Please let us know however if some (or none) of these worked for you.
