brand new subdomain: myphotos.mydomain.com
brand new MySQL database: mysql.myphotos...
brand new database: myphotos

Installed ZP into /zen/
Try to run setup

Fatal error: Call to undefined function getuserlocale() in /home/..../myphotos.woodengems.com/zen/zp-core/setup.php on line 81

Do you have a file functions.i18n in the install?

Yes, in the zp-core folder

Found the problem. Will probably have a fix in tonight's build.

Whew, better "your fault" than mine .
I created a new hostname AND new database. Picked a 4-image album, leaving everything as Default Theme/css. Therefore, when I do the 27-May update, should I overwrite EVERYTHING (yes, zp-config too) to isolate what could be wrong with my Slideshow?

sbillard: The 1612svn installed corrected the problem perfectly. Well, that is, once I remembered about the subdirectory path
