Is there any way to prevent blocks from being moved around? Although it's a powerful feature, I can see lots of clients messing up sites by doing this - not least because you'd have to account for the *possible* changes a client would make in the CSS...

Thanks

Check out the advanced permissions model: That gives you allot more control, but it doesn't single out "move" as specific permission. It does however allow you to set permissions by area, so you can keep folks out of navigation, sidebars, headers & footers so you can confine them to the simpler content. You can also confine users to specific block types.

I am running Concrete5 5.3.3.1 on in-house test server, and installed template "Orange Sunset", which was fine until I attempted to login as administrator again a day later and there was no "sign-in" prompt on home page.

how can I login otherwise?

I tried ip-address/admin, ip-address/administrator, ip-address/login, ip-address/sign-in, ip-address/manager, etc.

Nothing worked.
