Hi everyone,

I have added a file with a ISBN code for the firts time, the file uploaded normally without any problem but then Zotero refused to sync. I tried to delete the file, add new files, close and reopen but nothing seems to be working. The current error message displayed is the following :

[additional errors removed — D.S.]

ZoteroObjectUploadError: Parent item G6HLXJRP not found"]

[JavaScript Error: "Parent item G6HLXJRP not found" {file: "chrome://zotero/content/xpcom/sync/syncEngine.js" line: 1365}]

[JavaScript Error: "HTTP GET https://api.zotero.org/users/17303361/settings?since=1492 failed with status code 500:

An error occurred"]

[JavaScript Error: "Made no progress during upload -- stopping" {file: "chrome://zotero/content/xpcom/sync/syncEngine.js" line: 1424}]


Thanks lots for any help!
