Hello,

I cannot get rid of:
Fatal error: Call to undefined function printFavoritesURL() in /htdocs/zenphoto/zp-core/zp-extensions/favoritesHandler/deprecated-functions.php on line 10
error message at the bottom.

"printFavoritesLink (favoritesHandler)" check-box is unchecked in Options->Plugin-> deprecated-functions.

Please help. This looks like a common problem. Google returns a bunch of sites with this error.

Version 1.4.6, (May 26, 2014), default theme.

Your theme appears to be calling the favorites link function in spite of the fact that the plugin is disabled.

Also, just so you know, the "default" theme was dropped on 1.4.6 in favor of the "basic" theme, so probably the version you have was never adapted to the changes. Try using the "basic" theme instead.
