I've set up Zenphoto on a life server.
Installed everything, including the albums + thumbs by ftp.
Copied the backup database, installed that too.
It works, but when I click on any album I get the error message:
"Zenphoto Error: the requested object was not found."

From the backend, everything is there and everything works.
But not on the front end.
What can I do to correct this?

Maybe this helps:
Fatal error: Call to undefined function: stripos() in ---/zen/zp-core/admin-functions.php on line 590

The album is here: http://www.dgdesk.com/zen/

If you get that error you are not using PHP 5 which we state as requirement.
http://php.net/manual/de/function.stripos.php

That's true, this server is running the 4 version.
But it works. I didn't follow all the instructions, as given in the faq. Once I followed them, my problem was solved.

do a search of the forum on this subject. You are the second to have the problem. There is a solution posted and there is a fix in the 1.4.1 beta release.
