CLIENT201: Out of memory
What this means
This device ran out of memory, and the last action may not have finished.
Close other apps or tabs, restart WCPOS, then check your last sale or change saved. If it didn't, do it again.
Your data
The result couldn't be confirmed — check before trying again. If you were saving a sale or change when the memory ran out, check it saved before doing it again.
Troubleshoot
- Close other apps or browser tabs — WCPOS shares the device's memory with everything else running on it.
- Restart WCPOS.
- Check your last sale or change saved before doing it again: look at Store health → Database (a sale counted under changes waiting to send is saved and still sending), the cart, and Orders (WCPOS Pro) or WooCommerce → Orders. If a card was involved, check the terminal or the payment provider too — if the customer was charged, don't charge again. Only if it really didn't save, do it again once.
- If a specific action reliably runs out of memory, note what it was, tap Copy debug info on the Logs tab and contact support.
- If this happens daily on the same device, the device may be too small for the catalogue — report it so support can confirm.
