This error shows up when you try to ship an order through Auto Ordering, but Auto Ordering itself hasn’t been enabled for the store yet. Instead of the Make Order button, the order page shows an Error status with “AO mode disabled” — and you can’t ship through AO in this state.
Quick fix: the error block itself includes a link straight to the Automatic Ordering settings, so you don’t need to hunt for the section.
Step 1: Enable Auto Ordering
Go to Store Settings → Automatic Ordering (or use the link in the error block).
Check the Enable box.
Optionally configure other settings — e.g. “Mark shipped after AO is completed”, so the order is automatically marked shipped once AO finishes.
Click Save.
Step 2: Check your AO account
Auto Ordering runs through a connected supplier account (e.g. Amazon) that EaSync uses to buy the item. Make sure that account is added and in good standing.
Go to Fulfillment Methods → Fulfillment Accounts.
Check that the right account (e.g. amazon) is attached to your store, the Enabled toggle is on, and its status is Checked.
Step 3: Place the order
Go back to the order page. If AO is enabled and the account has no issues, the “AO mode disabled” error is replaced by a warning that AO is enabled and the order is ready to ship — with a Make Order button right in that block. Click Make Order and wait for it to ship — from here the order follows the same path as in Method 1 (the Orders History block, with statuses Ready → Start → Done → Waiting Tracker → Tracker Obtained).
