My b2evolution Version: Not Entered

I have tried for more than an hour and can't do a fresh install on a hosted server. I'm installing the latest version.

I created the mysql database on my site, but when I put the info in the first screen of B2, it says check your database settings and try again.

I tested the connection to mysql using a php script and it works. Should I change permissions on something?

What could be the issue?
