[JavaScript Error: "Error: Error(s) encountered during statement execution: FOREIGN KEY constraint failed [QUERY: INSERT OR REPLACE INTO itemTags (itemID, tagID, type) VALUES (?, ?, ?)] [PARAMS: 1052, 6275, 0] [ERROR: FOREIGN KEY constraint failed]" {file: "chrome://zotero/content/xpcom/db.js" line: 680}]

Check your database integrity from the Advanced → Files and Folders pane of the Zotero preferences. If it finds errors, please let us know.

If it still fails, restart Zotero and provide a Debug ID for an import attempt that fails (but restarting might just fix it).
