I installed Zenphoto 1.2.4 on my ubuntu server without any problem.

however I cannot acces to any of my albums. When I click one theme I get a 404 error:
Not Found

The requested URL /zenphoto/myAlbum/ was not found on this server.
there is a mistake in the redirection.

The link is:
http://www.mysite.com/zenphoto/myAblum but it should be:
http://www.mysite.com/zenphoto/albums/myAblum

The folder myAlbum is in /zenphoto/albums

I cannot figure out where is the misconfiguration.

Thanks for your help

First, you should really read the troubleshooting guide. (It is liked in the "read before posting" thread.

Most likely your server does not support the apache mod_rewrite and you have set the option to use that. (situation described in the troubleshooting guide--multiple possibilities.)

Also, if mod_rewrite is in fact working then the URL would look just as zenphoto has made it. (explaination in the troubleshooting guide-#4)
