i have looked at console and no errors
What did you do on the console to check errors?
Did you have a backup of your database?
Did you manage to see the installer after coping LS2.0 on the server?
If the installation went wrong, you might try a fresh installation in a different directory with a new database to see if the server is compatible.
Or you backup application/config/config.php and delete the file and try to run the installer again. If you always used the same database you might have mixed tables in it.
You might clean the database by hand or restore your database backup first.
Personally I would never do an upgrade without having tested a fresh installation first.
You always need a fallback if you're running LS in a productive way. And with an direct upgrade you risk you're best known installation becoming unavailable.
