so is every other file in the zenphoto dir. Yes it's unzipped correctly. Yes they're all blank on the local mac and my online webserver. Yes I've tried with php5 and php 4.
Yes every file has proper permissions & chmod 666.
Yes when I open the files in a text editor I see all their contents.

what else is there?

Yes, I edited the config.php and zenphoto/index.php is connecting to the database properly, but zenphoto/zen/setup.php is still just a blank page to me.

what type of webserver are you using?

online the server I'm on has
Apache/1.3.33 Unix mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4 PHP/4.3.10 FrontPage/5.0.2.2635 mod_ssl/2.8.22 OpenSSL/0.9.7a

offline my mac mini is running whatever version of apache came with it and php5

Do they have php short tags enabled?
short_open_tag needs to be set to true in your php config file. If this is not enabled then you will receive a blank page..

If you cannot change your php.ini file then you could always do a find and replace for
'<?' with '<?php'
and '
<?=' with '<?php echo '

yip short tags is turned on.

ya know what, how bout I just sign up for a dreamhost account, yeah I think i'll do that.

I am having this same problem:

short_open_tag = On

This is with whatever Ubuntu Breezy has. PHP 5 and Apache 2. phpinfo works

are you able to turn on Display_errors = On in your php.ini file to see where it is erroring out at?
