Zotero experienced an error updating your document (Google Docs on Chrome and Safari)

edodoo

My citations have been loading for hours now (on red bar), but never get updated in my Google Docs. Then, I get the error "Zotero experienced an error updating your document". I have restarted my macbook two or three times and updated my Zotero, yet I still experience the same errors.

If anyone has any solutions, please help! Thanks.
