SYNC131: Store server error
What this means
Your store returned an error, so this action did not complete.
The store was reached but its server failed to handle the request. This is a problem on the website rather than the POS, so retrying alone may not help: check the site's error log or ask the host to, then retry. Nothing was lost on this device.
Your data
The change is saved on this device but has not reached your store. If this persists, export diagnostics and contact WCPOS support.
Troubleshoot
On the POS (cashier): expand the log entry and note the status, endpoint and serverCode — they say what the server was doing when it failed.
On the website (site admin / host):
- Open WooCommerce → Status → Logs on the site and check the newest fatal-errors log around the failure time; a 500-class response almost always leaves a PHP error there.
- If the failure started after a plugin, theme or PHP update on the site, suspect that change first and roll it back or disable it.
- If WooCommerce's logs show nothing, ask the hosting provider for the server's PHP error log for the same time window.
Then, back on the POS: once the server-side cause is fixed, retry — the change is still saved on this device.
