I can't sync my data to the web library even pressing the sync button manually. Could you give me some suggestions for this problem? report ID:1837514931
Your database is corrupted, which generally happens from having your Zotero data directory in a cloud storage folder or network drive. If that's the case, you should move it back to the default location.
You can try to fix the damage with the DB Repair Tool. If that doesn't work, and your data is all online, you can just delete the zotero.sqlite file (or move it somewhere temporarily for backup) with Zotero closed and then reopen Zotero and sync to pull down your library. If your data isn't all online, you can sort your library by Date Modified, export those items to Zotero RDF, (back up and) delete and sync your library, and the import the RDF.
