Good afternoon,

I've duplicated a theme and done what is written in the next tutorial : http://www.zenphoto.org/news/theming-tutorial

And also changed the name of the previous theme in each php files where it appears .

But i've the next error message :
" Fatal error: Call to a member function theme_head() on a non-object in /www/***/themes/Sunny/album.php on line 14 "

Thanks a lot anyone for replying.

Did the theme you copied work originally? This error is from trying to reference an album object without having instantiated it.

Hi,

Yes you're totally right.
In fact the theme had a parse error, and i could see the original error by using directly the theme as the main zenPhoto theme and not as an album theme.

Thanks a lot , great answer.
