I constantly get this message at the top of my screen:

Notice: Constant DEBUG already defined in /home/fhlinux170/v/domain.com/user/htdocs/zp-core/functions.php on line 32

Do you know how I loose it please?

Cheers

You can delete that line. Or you can upgrade to the nightly build.

Sorry, how do I delete that line or upgrade to the nightly build?

There is a link to the nightly build on www.zenphoto.org on the right hand side. Best you download it and install it. It installs just like the 1.1.3 release. Be sure to run setup.php after uploading the zenphoto files.
