SYNC101: Local DB write failed
What this means
WCPOS couldn't write a change to this device's storage.
Free up device storage, then check the change shows up. If it's missing, enter it again. Contact support if it repeats. Until you have checked, note what the change was — if WCPOS closes before the change is written, it is gone. Don't clear this device's data.
Your data
Don't clear this device's data — it may hold sales that haven't reached your store. The change that failed may not be saved anywhere yet, so keep a note of it until you have checked it shows up. If this keeps happening, use Copy debug info on the Logs tab and contact WCPOS support.
Troubleshoot
- Note what the change was — the record and the values you entered. If the log entry names a record, that is the change that may not have been saved. Site and credential writes may name only the failed operation and error instead; note those details too.
- Do not clear site data, reset the app, or uninstall: other changes that haven't reached your store yet, such as sales, exist only on this device, and clearing local storage deletes them permanently.
- Free up device storage by removing other files or apps — a full disk or an exhausted browser storage quota is the most common reason a local write fails. Don't use the browser's "Clear browsing data" to make room — it deletes WCPOS's unsent sales too.
- Check the change shows up — open the record. If it's missing, enter it again and save. If it still won't save, restart WCPOS once and try again.
- If saving keeps failing, use Copy debug info on the Logs tab and contact support before attempting any repair.
