Notice: Debug-Mode is enabled! appears without _XHdebug.txt

[svasti]

Hello respected experts,
I got a strange problem with a new XH 1.4 website. After login it says:

Notice: Debug-Mode is enabled!

But I have no _XHdebug.txt file in Downloads. So this notice should not be there. I uploaded a new CMSimple_XH 1.4 and it is still there. However, when I use a subdomain linked to the same files on the server, the debug notice is gone. Main difference in php Info (PHP Version 5.2.8):

Domain:
display_errors: local value On master value: On
error_reporting: local value 2039 master value 0

Subdomain:
display_errors: local value Off master value On
error_reporting: local value 0 master value 0

Anybody any idea?
My experience with the provider is that he will simply say: "There is a mistake in your scripts."

Any help will be appreciated

Well, sort of solved: after many emails the provider finally set display_errors to Off. Now the problem is gone.
Sometime on shared hosting there are strange php-settings.
