@adomasven No, local storage... But I am pretty sure it was some linux/wine issue. I didn't mention what OS I am using. I am aware it is not officially supported. I've fixed it by modifying "zotero.dotm" file. More here: https://forums.zotero.org/discussion/12426/word-intergration-with-wine/p3 I don't know if this error can occur also on windows/mac.
zotero an unhandled exception occured. getdocument:document.cpp
I don't know if this error can occur also on windows/mac.
