If you are receiving a translator error when using the Chrome extension, it could mean many things. Refer to the Zotero page about translator errors. If none of these relates to your error, confirm how many results you are trying to add to Zotero. For EBSCO databases, Zotero works best when the number of results per page is set at 30 or lower. If the error was related to one resource, you can add the resource manually by referring to the Adding Resources to Zotero tab.
Zotero will sometimes not add resources to your collection. In some cases, you will see a translator error and will need to refer to the suggestion above. Other times, Zotero may lock you out if you are using Google Scholar or ProQuest and too many results are being exported at once. You will not see an error, however resources will not appear in your collection. If this has happened, your privileges should be restored in a few hours or refer to Zotero's site access limits page.
Zotero has a forum where other users have posted questions about using Zotero or issues they had. You can also post your own question on the forum or search for a resolution to an issue you may be experiencing with Zotero.
