I have two sites on Zenphoto version 1.4.1.1 [7644] (Official Build), both with a modified Default theme. Both have the same problem: although the Admin Toolbox shows (when I'm logged in) clicking it does nothing. It works if I change to the Default theme, so it's obviously something I removed in my custom theme. I only noticed it now that I want to create Dynamic Albums, and I think the Admin Toolbox is the only way to do that. I know it's not much to go on, but any ideas?

Does this fail on a not modified default theme? If not then it is something in your modifications causing it.

The click action on the admin toolbox is handled by a javascript function. So one of two things most likely has happened. First, the Zenphoto javascript support files did not get loaded. The particular function used is part of the zenphoto.js file.

The other possibility is that ther is some kind of javascript conflict/collision. So if you have loaded your own javascript it would be suspect.

So, be sure there is a line in the html loading the zenphoto.js script. Check if there are any javascript errors occuring.

Thanks for the quick response. As I mentioned in my OP, the Admin Toolbox opens fine with the Default theme applied, so it's something I changed. I haven't added any javascript, and I tried pasting the styles from the default CSS into my theme, and still no. I don't know how to ensure the javascript support files get loaded or how to tell. I'll keep digging.

My custom theme was based on a really old Default theme, so I applied my style sheet to the latest Default theme, made a few other changes and it seems to be working now. Now and then the AdminToolBox just doesn't show at all, but a cache clear fixes that. Still don't know why it wasn't working...

You answered yourself. Your browser cached the old version.
