When I click on "View Gallery" in the top-right corner of the screen, my address is directed to...

http://vizualight.com/zenphoto/

I then see two links for my album called "holidayacres," one with a box around it, and one that is underlined. When I click on either one of them, I get this same message...

"The requested URL /cgi-system/holidayacres/ was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."

Any help you can give me would be much appreciated...

Try setting the WEBPATH and SERVERPATH overrides at the bottom of zp-config.php, they do not seem to be correctly detected.

Could also be a problem with a RewriteBase in .htaccess. Make sure it looks like:

`RewriteBase /zenphoto`

What should I set the WEBPATH and SERVERPATH overrides to? I did correct the RewriteBase /zenphoto before I wrote this. Thanks for your help. Look forward to hearing from you again on this. I am using Dreamhost for my host.

Ahhh wonderful dreamhost...

Upgrade the PHP version to 5 for that domain. It's in the Domain Management control panel. Then go read this: http://www.zenphoto.org/support/topic.php?id=316&replies=25
