Hi Jim, follow up the question at the link http://omeka.org/blog/2010/09/29/zotero-import-plugin/
I still have the same problem. I installed omeka 1.3 with the latest plugin 1.2, I also tried omeka 1.2.1, 1.4 with plugin 1.2. But none of them works. Can you tell me what version combination you use? Any additional configuration needs to be done?
