My b2evolution Version: 1.10.x

Hi,

I've just installed "b2evolution-1.10.2-2007-06-08.zip".
When I want to go to the backoffice as "admin", I have this error :

Warning: main(/homepages/16/xxxxxxxx/htdocs/domain_name/blogs/skins_adm/legacy/_adminUI.class.php) [function.main]: failed to open stream: No such file or directory in /homepages/16/xxxxxxxx/htdocs/domain_name/blogs/_header.php on line 93

Fatal error: main() [function.require]: Failed opening required '/homepages/16/xxxxxxxx/htdocs/domain_name/blogs/skins_adm/legacy/_adminUI.class.php' (include_path='.:/usr/local/lib/php') in /homepages/16/xxxxxxxx/htdocs/domain_name/blogs/_header.php on line 93

I can go to http://domain_name/blogs/index.php, http://domain_name/blogs/index.php?blog=2, ...etc... but not in the backoffice.

I'm hosted by 1and1, I use Php 4.4.7 and mysql 5.0

Any help would be appreciated.

Regards,
