I just installed Zotero 6.04 and I get an error message during synchronization : Component returned failure code : 0x80570016 (NS_ERROR_XPC_GS_RETURNED_FAILURE) [nsIJSCID.getService].
[JavaScript Error: "Services.logins is undefined" {file: "chrome://zotero/content/xpcom/sync/syncLocal.js" line: 402}]
There's some problem with the login database in your Zotero profile directory. Could be some sort of file corruption in that folder, or could be due to security software on your system preventing Zotero from accessing its profile folder.
You can try deleting cert9.db, key4.db, and logins.json from your profile folder, restarting Zotero, and reentering your credentials in the Sync pane of the preferences. If that doesn't help, it's likely something else on your system interfering.
