I have over 16000 images in a file structure under zenphoto's album folder.
When I brought up the zenphoto gallery homepage for the first time everything worked great. After about 10 minutes or so my master album on the homepage disappers. I can still get to subalbums with a direct link:
http://HOSTNAME/zpcms/index.php?album=harvest%2F40
But I get a blank page when I try:
http://HOSTNAME/zpcms/index.php?album=harvest
http://HOSTNAME/zpcms gives me a homepage but no master harvest album in it ... the content is blank.

If I move the harvest folder to harvest_temp then everything works again for another 10 minutes or so.

I can't figure out what's going on and how to fix it. Please help.

Thanks

Did you review the troubleshooting article on our site? Most likely one of these:

I can't figure this one out. Is there a way to somehow disable caching?

When I move the master harvest folder to something else like so:
mv harvest harvest_temp

Then everything works great for a little while. I can page through the albums under the harvest_temp album. If I immediately move harvest_temp back to harvest eveything works for a little while. After a little while I can no longer see the harvest album and the only thing I can do is go to the direct subalbum links.

Anyway, I thought maybe it's a cache thing. Because there are so many images I thought maybe the cache system was struggling to get through them all and somehow screwing things up.

Let me know if there's a way to disable cache in the system and I'll try it.

I've disabled everything I could but can't seem to pinpoint the problem. I would really like to use ZenPhoto.

Thanks.
