Common errors
The most frequently reported SlotSmith error states and how to resolve each one.
On this page
“No delivery options available” on the storefront
Usually means the customer’s address doesn’t match any published zone, or the matching zone has no rules attached yet. Check Zones → [zone] → Rules — a zone with zero rules never produces slots.
A slot shows full when it shouldn’t
Check the rule’s capacity setting. A capacity of 0 means uncapped; any other number is a hard cap. If you meant “no limit” and typed a small number instead of 0, that’s the usual cause.
CSV import rejected the whole file
SlotSmith validates every row before creating anything, so one bad row fails the entire file. See Import troubleshooting for the specific error codes.
Billing usage looks stale
Usage in Billing → Usage updates in real time, but if you just published or archived a zone and the number looks unchanged, refresh the page — the admin UI doesn’t currently poll.
