Hi,
I've just run Zenphoto for the first time and in the Zenphoto setup i get this error message

Localization of Zenphoto currently requires native PHP gettext() support

all the other check are OK, what do I have to do for fix the problem?

Thanks

You will have to get gettext support included with the PHP on your server. The specific details I do not know. You need native gettext support only if you wish to use one of the languages other than English.

I'd like to use Italian lang, but I don't know how get the gettext support, I browsed Internet but without success

does anyone knows how install the gettext?

Vertigo : ask it to your hosting provider. (Do you host "at home" ?)
