Hello,

I recently had to move my zenphoto site from one datacenter to another. I have the same php/mySQL versions in both centers. I moved my files, created the zenphoto mySQL database, imported the old database into the new one. When I access the site, I get this error:

"Zenphoto has detected a change in your installation.

Zenphoto 1.4.5.9[12ad1f92fa] has been copied over an unknown release.
The change detected is critical. You must run setup for your site to function. "

When I click on the "setup" link or run it directly from mysite.com/zp-core/setup.php
I get this error:

"The mysite.com page isn’t working

mysite.com is currently unable to handle this request.
HTTP ERROR 500"

The zp-data/debug.log has this message:

{3556:Tue, 26 Jul 2016 10:16:43 GMT}
NOTICE: Use of undefined constant ADMIN_RIGHTS - assumed 'ADMIN_RIGHTS' in /srv/data/web/vhosts/mysiste.com/htdocs/zp-core/reconfigure.php on line 109
checkSignature called from reconfigureAction (reconfigure.php [12])
from require_once (functions-basic.php [181])
from require_once (admin-globals.php [12])
from setup.php [2]

Not sure what the problem is here - any hints?

OK, I did an upgrade to the latest version, 1.4.12, and it fixed the problem.
The site runs ok.

Ok, I can only assume this was a glitch of moving the site (missing htacces possibly or of course changed cookies/sesssion for the login).
