solution of the error "Could Not Save Item": Zotero and Web of science or other Web of Knowledge databases.

Currently Zotero not playing nice with Web of Science, or any of the other Web of Knowledge databases
e.g. error "Could Not Save Item. An error occurred while saving this item. Check Known Translator Issues for more information."

Please go to http://github.com/ajlyon/translators/raw/master/ISI%20Web%20of%20Knowledge.js and save the file to the translators directory of your Zotero data directory (http://www.zotero.org/support/zotero_data).

Restart Firefox, and it should start saving from all WoK/ISI databases. Currently, it saves all of the results for your current query-- that'll change soon, but the courageous can try it out now."

There are unresolved issues that make multiple item saves fail, so this is limited to one item per save at present (DATA@dec 2011).
