Cannot redeclare class JConfig

I get this error when i installed CB 1.1. Until today i made apr.15 CB installations. lot of errors i got, but this error i saw in first time.

After error i uninstalled everything from CB, and cleaned Database tables. But anyway site gave me Fatal error

Fatal error: Cannot redeclare class JConfig in /home/XXXXXX/public_html/configuration.php on line 2

Does anyone know what needs to be changed to make site up again?

I don't want reinstall everything again - there is installed and configured lot of Things - galleries, another components, forum ...

I found topic about this problem, but without any advice.


Anybody know - how to fix it???
