Fatal Error when Installing Plugins

I am trying to install some additional plugins to Omeka. I downloaded them to my computer and then uploaded them to my Dreamhost site using their WebFTP client, which has an "archives" option. "Archives entered here will be decompressed, and the files inside will be transferred to the FTP server," Dreamhost promises.

It seemed to work, and when I go back into my Omeka site I see the plugins ready to install. But when I click the green Install button I get an error message. In the case of the Dropbox plugin I see:

Fatal error: Call to undefined function get_plugin_ini() in /home/larrycebula/larrycebula.com/omeka/plugins/Dropbox/plugin.php on line 10"

Hi Larry,

What version of Omeka do you have on your server? We recently released the 1.0 beta, and upgraded pre-released plugins to be upgraded for this version. I ask because the error you're receiving could appear if you're trying to install an upgraded plugin on an older installation of Omeka. If that's the case, here's an archived copy of plugins for Omeka 0.10: http://omeka.org/add-ons/plugins/010-plugins/

Thanks, Dave, I will give it a try.

Success--I think. Thanks.
