Try chmoding the htaccess ans zp-core folders to 755

sbillard I've tried that already, no luck what so ever.

What do you get when you run setup.php?

Hi,
I've got the same problem... Tried everything...
Hope somebody'll find a solution...

Matteo and benmilo:

Can you post links to your sites so we can take a look?

Also, please review your CGI logs and see if there are any errors reported there. Finally, are there any indicators of issues when you run setup.php?

Hope you can find what's wrong!
Thanks
edit: no errors when setu.php runs

The HTML source looks very much like there was some sort of CGI error. Can you review the CGI error logs from your server to see what it shows? (This is not the same as the information shown by setup.php.)

Hi!
I can't access the cgi logs but I re-installed zenphoto and have this error:
"Notice: Constant DEBUG already defined in /var/www/vhosts/teamphysio.ch/httpdocs/zenphoto/zp-core/functions.php on line 32

Warning: Cannot modify header information - headers already sent by (output started at /var/www/vhosts/teamphysio.ch/httpdocs/zenphoto/zp-core/functions.php:32) in /var/www/vhosts/teamphysio.ch/httpdocs/zenphoto/index.php on line 12"
the website is now on www.teamphysio.ch/zenphoto/

I installed zenphoto on another site (same provider) and it works fully...

The DEBUG problem is because somewhere else, most likely in zp-config.php. Some versions of PHP complain about this. It does not really hurt anything, but there is a fix in the nightly build for this.
