Connection to the shop

Message or symptom Solution
A feature is grayed out: "Requires updating the psmanager module" Download the up-to-date module from the app and upload it in the back office (it replaces the old one)
The connection test fails with the Admin API The PrestaShop 9 Admin API requires HTTPS: check the shop address (https://) and the certificate
The "Connecter One Shop Manager" button does not open the app Use "Copier le lien" (Copy link) under the module's code, then paste it into the app
Development shop with a self-signed certificate or protected by a password In the profile: "accept a self-signed certificate" and "Password-protected site"

Synchronization

Message or symptom Solution
"Data needs refreshing" on the dashboard Click "Sync"; the catalog then the sales are updated
Figures inconsistent with the back office "Full resync" rebuilds the local cache
"Offline" in the sidebar Changes wait in the Send queue and will go out when the connection returns
A line comes back "in conflict" The product has changed on the shop since the sync: check the current value, then rerun from the log

License and payment

Message or symptom Solution
"Online purchase is not open yet" Write to contact@oneshopmanager.com to get a key
"License server unreachable" Check the Internet connection; without contact with the server, the license remains valid for up to 7 days
"Update not covered" Renew one year of updates, or reinstall a version released before the end of your updates
One computer too many (more than 3) Release an old computer from the customer account

Order picking

Message or symptom Solution
"Mark as shipped" stays grayed out The parcel check is not finished: scan each item, or use +1 per line or "Everything is in the parcel"
An order is "Being picked" on another computer It is locked by that computer; the lock is released when it leaves picking, or on its own after 2 hours without activity

Still stuck?
