Troubleshooting
Printer not printing, no internet, forgotten PIN, device won't pair, missing emails and other common issues.
Printer doesn't print, or the print dialog opens
- Make sure the thermal printer is the default printer in Windows and that the paper width (80/58 mm) matches the setting on Dashboard → Team & devices → Kitchen & printers.
- To print without the print dialog, start Chrome with the
--kiosk-printingflag: right-click the Chrome shortcut on the desktop → Properties → add--kiosk-printingto the end of the Target field. - If kitchen tickets don't print: check that the product/category is linked to a station and that the station has a printer (Stations).
- Tickets from waiter phones print from the POS computer set in Which POS should print?; the POS must be open on that computer.
No internet / "Can't reach the server"
- The POS and waiter app work offline: keep selling. Actions wait on the device and are sent when the connection returns. Don't close the browser or reload the page.
- If the connection icon in the top bar is red, check your modem/Wi-Fi.
- The dashboard and reports need internet.
Forgotten PIN / "Wrong PIN"
Dashboard → Team & devices → Staff → open the person → set a new PIN. If the business owner forgot their PIN, they log in to the dashboard with email and password and change it on their own card.
Device won't pair / "This device is not paired"
- The code is valid for 15 minutes and can be used once; get a new code from Dashboard → Team & devices → Devices if needed.
- Clearing browser cookies/history removes the pairing; pair again.
- Pairing in a private/incognito window doesn't persist; use a normal window.
- If you've reached your plan's device limit, no new devices can be added: remove an unused device or upgrade your plan.
Customer display won't open
The browser may have blocked the pop-up: use the icon in the address bar to allow pop-ups for this site. If you use a separate tablet, make sure it is connected to the internet.
Emails don't arrive
Check your spam/junk folder. For notification emails, make sure Settings → Email notifications is on and the address is correct. Password reset links are valid for 1 hour.
"Session expired"
For security, sessions with no activity for a long time are closed. Reload the page and log in again. Unfinished work at the POS is not lost.
QR menu doesn't open or is outdated
Make sure the phone scanning the code is online. If Regenerate QR was used, old table cards stop working; print them again. If you changed the QR menu address (Settings), regenerate the general QR code too.
