I was having problem with Gallery3 and decided to give this a try. I really like what I have seen but I have not been able to get the search function to work. I have changed theams and reloaded the whole program a couple times to no avail. As soon as I upload photos and try to search i get a completely blank browser. Any suggestions? I'm hoping it is just a setting issue I cant find.

Please find your PHP error logs and report the error you are getting. (See also the forum rules for other information that might be necessary.)

I am having a similar issue. I get a blank page when I click on the tags of an album. I have a couple albums with the same tag. My site logs say:

20120913T175257: [MY SITE NAME HERE]/Zenphoto/index.php
PHP Fatal error: Call to a member function albumSubRights() on a non-object in /hermes/waloraweb083/b770/[MY SITE HERE]/Zenphoto/zp-core/class-search.php on line 1257

Install the nightly build. I believe this is fixed therein.

zenphoto-2012-09-12-trunk.zip worked for me, thanks!
