I am using version 1.2.2 of Zenphoto.

There is a problem with a password protected albums.
Everytime after I have written both, the username and the password, the soft will ask them again. After this has happened a couple of times there appears an error warning:
"Fatal error: Call to a member function getPrevImage() on a non-object in /home/taikalyh/public_html/galleria/zp-core/template-functions.php on line 1814"

The problem only appears when Interne Explorer ( any version of it ) is being used to see the page.

You will need to upgrade to the current version of zenphoto. I suggest you wait until next week as version 1.2.4 will be available then. If you do not want to wait, get the nightly build. It is pretty much what zenphoto 1.2.4 will be except maybe a few fixes if something shows up between now and the weekend.
