Thank you Ipstenu for reply.

it is a fresh installation, without any plugins.

It is probably not a server problem, 2 servers are placed 100 milles away from each other, both in Slovenia, but different hosting providers managing them.

I’ve seen couple of posts of people with similar problems, but you are right, it can’t be a general problem. I am thinking that it might be either UTF-8 or language related (even though it sounds weird).

We use ????? and similar letters in Slovenia and also IE comes in Slovenian language. I suspect it is to blame, but not sure.

So I kindly ask again any Windows user from anywhere else but Slovenia to try to log on with INTERNET EXPLORER on the test account:

user/loginuser

Thank you!

Depends on what you want to achieve, but both options are possible.
If you choose mutisite, you can share users, plugins, themes,…
If you choose separate wordpress, than you can use different configurations…

I would suggest to use multisite option, it seems like the wordpress way…
