# Troubleshooting

1. Reproduce once in a private browser window and record the exact time, page and message.
2. Open **Sync & Logs**; check database, Cron, Square token, last sync, webhook signature and failed jobs.
3. Clear page/CDN caches and exclude the booking/manage/staff pages from full-page caching.
4. Temporarily test with a default theme and only Yatoon enabled on staging to identify conflicts.
5. Confirm WordPress/PHP time zones, business hours, breaks, closed dates and staff-service assignments.
6. Download the redacted diagnostics package before changing settings.

Do not send access tokens, webhook secrets, full customer exports or reference photos in ordinary email. For failed upgrades, use the pre-upgrade snapshot and the migration status shown in Sync & Logs.
