Honestly getting tired of constant issues with zenphoto these days ... it used to be so low maintenance!
Anyway - its probably something stupid on my part, but for some reason only admin accounts can see images. Depending on which normal account is logged in, they can see different albums... some can see one album, others can see 5 or 6 but with ? as the album thumbnail and then no images inside it.
It's a private gallery, and I have run it for 4 or 5 years now so I usually know what I am doing with permissions etc. All albums are published, all albums are fully functional with any admin account, all normal users have view gallery, view full images, post comments etc etc.
The server move went "otherwise" without a problem. I moved over the albums to the new server, slapped on a fresh upload of zenphoto and ran the upgrade all without errors.
Someone wanna give me a cluestick here?
