SMF requires at least PHP 4.1.0 or higher. That error means that you have too old a version of PHP installed to use SMF.

Ask your host to upgrade PHP.

Wow, that version of PHP must be really really old... cavemen wrote it or something.

Just a little question, how can you know which version it is, just seeing those errors?

I'm not one to know, but it seems that everytime you tell support what the errors say they know exactly what the problem say. I'm guessing it's their experience

Yeah, the errors are cryptic but they mean something to us.... it's something you learn over time .

Some errors do have special meaning to help figure out the problem. $_SERVER  was added in PHP 4.1.0... so if an error appears saying that it doesn't exist it means that your using an older version than 4.1.0. Same goes for $_COOKIE, $_SESSION, $_ENV, $_FILES, $_GET, $_POST, and $_REQUEST. If any of those give errors saying they don't exist then it's an older version than 4.1.0.

Thank you for support.  I asked my hoster, what version of php it have, an he say that 4.0.6.
Now i understand what is the problem.
One more time thank you. I trying to do something with it.
