Well, I think I have it installed. I can get to the admin section but there are a lot of goofy things going on:

1. I have to log in after every submit, it seems.
2. I get these errors (or warnings):
   Warning: Cannot modify header information - headers already sent by (output started at /home/kaline/public_html/gallery/zen/config.php:103) in /home/kaline/public_html/gallery/zen/auth_zp.php on line 22

Warning: Cannot modify header information - headers already sent by (output started at /home/kaline/public_html/gallery/zen/config.php:103) in /home/kaline/public_html/gallery/zen/auth_zp.php on line 23

3. I tried to create a new gallery and upload pictures but I get this error:
   "Something went wrong...
   You must upload at least one file."

If there is anything I can provide that will help, please let me know. If you want to try it out and see the errors I'm getting, just go to:

and log in with admin admin

Thanks in advance!

OK. I figured it out.
In the config.php file, there was extra space after the closing ?>
I removed all of these blank lines/spaces, saved it, and now it works. I had this same problem a few minutes ago with a textpattern upgrade. Ugh. Hopefully this helps somebody out there.

Looking forward to testing this out. I've successfully created an album and loaded some pictures to it. Woo hoo!

Yep, that's what I was going to say... sorry for that quirk, but there's no way around it.

Thanks for trying it out and have fun!
