Strange problem.
On my installation zenphoto few people can't go deeper than start screen - error Page don't exist.

In apache log I got error:
File does not exist: /path..to..zenphoto/portrets, referer: http://blah...blah.com/

It's looks like not rewriten address becouse proper address should be
/path..to..zenphoto/albums/portrets????

Or I miss something?

So what does setup report about modrewrite? Did you try to disable modrewrite? Zenphoto links never point to the "albums" folder itself!
Also please review: http://www.zenphoto.org/2009/03/troubleshooting-zenphoto/

I read this already.
When I turn off modrewrite - everything works fine.
And I know that fact about links.
But strange is this: on some machines moderewrite works fine (I check this on my laptop with OSX, Safari, and PC with Firefox or IE), on other - not (My friend PC with Firefox...). Maybe some plugins? Where I should look to catch the point?
Thanks anyway for response.

If modrewrite works or not is a matter of the configuration of your server and has actually nothing to do with the computer someone visits the site from.

Yeah, maybe you right - but question is: why on some computer this error apear, and on other not?
And this is not random.
If someone can't open album - then reloading page, using other browser - don't change anything.
In other side my computer and few other people tell me everything is fine.
So - strange...
Thanks for response. :-)

Sorry, then the only thing that comes to mind might be a browser issue like a outdated cache file for example which can play funny tricks. Or the visiting computers have a wrong firewall configuration or else.

If it is not random you need to find out what all the machines it does not work have in common. Modrewrite is a server configuration option.

I think i got problem.
When in browser I wrote http://www.blah..blah.com - everything works fine, I can browse whole gallery.
But when somebody wrote address like this: http://blah..blah.com (without www) - then I can browse only mainpage - if I want go deeper into gallery got error: Not Found. The requested URL ...... was not found on this server.
How to fix that?

Are you sure your server is configured to use the domain with and without the "www"? Please try if this is a general issue and if contact your host.

My start page works and dosn't mather with or without www in address, so I suppouse my server is configured properly. Problem starts when I try go deeper in gallery - then without www and with modrewrite ENABLED I got error "Not Found". If I turn off modrewrite, then I can go deeper withou problem.

Resume:
http://www.blah...blah.com - works
http://blah...blah.com - works
http://www.blah...blah.com/portraits/ - works
http://blah...blah.com/portraits/ - ERROR: "Not Found" (with mode_rewrite ON)
http://blah...blah.com/index.php?album=portraits (with mode_rewrite OFF) - works

So again - how to fix that? Any Clue?

Sorry, I have no idea. I tried it on another site without any problems (shared hosting).
