After I applied update to our Gallery Section of our web site which is running ZENphoto we not get the following error messages.

Warning: require_once(/hermes/bosweb/web072/b729/sl.brightonastro/public_html/photos/zp-core/global-definitions.php) [function.require-once]: failed to open stream: No such file or directory in /hermes/bosweb/web072/b729/sl.brightonastro/public_html/photos/index.php on line 4

Fatal error: require_once() [function.require]: Failed opening required '/hermes/bosweb/web072/b729/sl.brightonastro/public_html/photos/zp-core/global-definitions.php' (include_path='.:/usr/local/lib/php-5.2.17/lib/php') in /hermes/bosweb/web072/b729/sl.brightonastro/public_html/photos/index.php on line 4

I have tried to look for the missing files but did not find them, and they are not in my backups.

So I'm not sure how to recover out side of reinstlling everything.

That file should have been part of the zenphoto package. You should download the release again. Did you get through the setup process?

I did the inital install thru the startlogic contol panel, and there is also where I did the update as well, so it handle all the downloading installing since they are host our web site.

Please read the forum rules or the installation page regarding 3rd party install tools. Please perform a manual install or you have to contact the provider of this install tool.
