Hi,

After extract files on my ftp, i have a problem with the link : http://boutaboutsarl.fr/zenphoto/
That's a problem with php with my webhost ?
i see actually on this link : ' . $_contents; @eval($_contents); if (@$_zp_conf_vars['site_upgrade_state'] == 'closed') { if (isset($_zp_conf etc.... etc....

Thank you for your help

Looks indeed if something is wrong. Could be permissions or something went wrong uploading. So for now try reuploading (maybe without extracting on the server but before that).
