Report ID: 477331252
I hope someone can help with this. I got this message on trying to sync my library: "An error occurred during syncing: Cannot edit item in library 1834710" I never had this issue previously: syncs were always successful. I have no idea what could have caused it. I closed my last session of Zotero properly and had no trouble starting it a few hours later. Only now syncing gives me this error message. Thanks for your help.

Database upgrade error
Error: Error(s) encountered during statement execution: UNIQUE constraint failed: itemRelations.itemID, itemRelations.predicateID, itemRelations.object [QUERY: UPDATE itemRelations SET object='http://zotero.org/users/4096550/items/72Q7PKVG' WHERE itemID=?

<<Message end>>
Following the message, I am given the options to "Quit" or "Check for Update". Since I already updated to the latest version, Zotero tells me "No Updates Found" and gives me only a "Quit" option.
I hope this provides sufficient information to enable a solution to the problem. Since Zotero does not load the database, I cannot send you a Report ID or a Debug ID.
What am I to do? Thanks for your help.
