Piso WiFi Admin Page Will Not Save
An admin page that loads but will not save is frustrating because it looks like the machine is working, until you discover that every change was lost. Rates, pause settings, WiFi name, portal settings, and voucher settings can all appear to change in the browser, then revert when you reload the page or reboot the machine.
This post is mainly for operators. Customers should not change admin settings. If you are a customer and an operator tells you a setting will not save, the useful action is to note the setting, the time, and the portal result, and let the operator work through the checks below.
Answer first: If an admin page loads but will not save, log out and log in again on the machine network and try one small change. If that fails, check the mode and profile for the section you edited, then check storage, because a failing microSD card or full storage can lose changes on reload or reboot. Do not factory reset as a first step.

Symptom Check: What Exactly Fails to Save?
Note your pattern before you change anything else, because the cause depends on it.
| Pattern | What it may mean | First check |
|---|---|---|
| Every setting fails to save, across all sections | Storage fault, session fault, or a read only configuration | Check session, then storage, before changing settings again |
| Only one section fails, such as rates or pause settings | Wrong mode or profile, a section specific save step, or a partial storage fault | Check mode and profile for that section first |
| Save appears to work, but the change is gone after reload | Change was held in the browser only, not written to storage | Reload the page and check again before rebooting |
| Save appears to work, but the change is gone after reboot | Storage fault, or a backup restore or rollback overwrote the change | Check storage, backup date, and update history, as in the Rates Reverted After a Reboot guide |
| Save button is greyed out, or the page shows an error on save | Session expired, permission issue, or a platform fault | Log out and log in again, on the machine network, and try one small change |
Do not keep changing settings repeatedly while saves are failing. Each failed save can leave the machine in a mixed state, with some settings old and some new, which is harder to diagnose than a single failed change.
Likely Causes, in Order, for Operators
Cause 1: Admin session expired
Admin sessions can expire, especially after a long time on the settings page, a network change, or a switch between WiFi and Ethernet. A page that was loaded before expiry may still look editable, but saves will fail because the session is no longer valid. Log out and log in again, on the machine network, and try one small change. If the small change saves, the cause was session expiry, not storage.
Cause 2: Wrong mode or profile
Rates, pause settings, and portal options can differ by mode, such as coin mode versus voucher mode, or by profile, such as a weekday profile versus a promo profile. If you edit one mode and test another mode as a customer, the change will look like it did not save, even though it saved in the wrong place. Check the mode and profile for the section you edited, and test as a customer in that same mode.
Cause 3: Failing storage, such as a failing microSD card
Small board machines often store settings on a microSD card. A failing card can load the admin page normally, accept a save in the browser, and then lose the change on reload or reboot. Other signs include settings reverting together, reboots, freezes, or a backup that fails. This is the most important cause to rule out early, because it affects every setting, not just one.
Cause 4: Storage full, or a backup or update in progress
A full storage device, a backup running in the background, or an update process can block a save. Check storage space, backup status, and update status for your platform before assuming the card is failing. Do not start an update while saves are failing, because an update on failing storage can make recovery harder.
Cause 5: Browser, network, or device problem on the admin device
A stale browser page, a VPN, a switch between WiFi and mobile data, or a weak signal on the admin device can interrupt a save. Test from a second device on the machine network, in an incognito window, with VPN off, before concluding the machine storage is at fault. If the save works from a second clean device, the cause was the admin device, not the machine.
Operator Fix Order, Labelled as Operator Only
- Note the platform, version, setting changed, mode and profile, time, and whether the change disappeared on reload or only after reboot.
- Log out and log in again, on the machine network, and try one small, safe change, such as a portal label or a test rate in the correct mode. If it saves and survives a reload, session expiry was likely, and you can continue carefully.
- Check mode and profile for the section that failed. Correct the setting in the mode and profile customers actually use, and test as a customer in that mode.
- Back up settings if the panel still allows it, and note the licence key and version, before you change storage or update anything.
- Check storage: card health, storage space, backup feature, and whether other settings also revert. If several settings revert together, treat storage as the likely cause.
- If storage is failing, replace it through the supplier’s official path for your platform, restore from the most recent good backup, and re-enter any settings that were lost, in the correct mode and profile.
- Save, follow any reboot prompt from the platform, reboot once more, and test as a customer with a small payment. Only reopen to customers when the change survives a reload and a reboot and matches the sign.
- If saves still fail after session, mode, and storage checks, contact the supplier with the platform, version, setting, error message if any, storage check result, and backup date. Do not factory reset as a first step, because a reset can wipe rates, WiFi name, passwords, vouchers, and sales history, as explained in the WiFi Name Changed After a Reset guide.
What Not to Do
- Do not factory reset to fix a save failure, unless the supplier guide for your platform says to do so for this fault, and you have a backup first if the panel still allows it.
- Do not update firmware while saves are failing, unless the supplier advises it, because an update on failing storage can make recovery harder.
- Do not change several settings at once while saves are failing. Change one setting, save, reload, and confirm, so you know which change worked.
- Do not share admin passwords, licence keys, or backup files in public groups to get help. Share them only with the supplier, through the supplier’s official support channel, if needed.
Proof and Records to Keep
Keep a private record: platform and version, setting changed, mode and profile, save result on reload, save result after reboot, storage check result, backup date, and test payment result. That record helps a supplier diagnose a storage fault quickly, and it helps you avoid re-entering the same lost setting repeatedly.
Prevention
Prevention is a backup and test habit: back up settings regularly, note version and licence key, and store the backup privately. After any important change, save, reload, reboot if prompted, and test as a customer before reopening. Replace storage at the first sign of repeated save failures, rather than waiting for a full settings loss. Keep a written settings record, with date, mode, profile, rates, WiFi name, and pause settings, stored privately, not on the machine sign.
Frequently Asked Questions About an Admin Page That Will Not Save
Why does the admin page load fine, but my change disappears?
Loading a page and saving a change use different paths. A page can load from memory or a cached copy, while a save must write to storage. Session expiry, wrong mode or profile, and failing storage are the most common reasons a visible change does not survive a reload.
Is a failing microSD card the only storage cause?
No, but it is the most common storage cause on small board machines. Full storage, a backup or update in progress, and a platform specific storage fault can also block saves. Check session and mode first, because those are quick, then check storage before replacing anything.
Should I factory reset if saves keep failing?
No, not as a first step. A factory reset can wipe rates, WiFi name, passwords, vouchers, and sales history. Back up first if the panel allows it, check storage and supplier guidance, and reset only if the supplier guide for your platform says to do so for this fault.
Can I fix a save failure from my phone as a customer?
No. Admin settings are for the operator, on the machine network, with the admin password. A customer should report the setting, the time, and the portal result to the operator, and let the operator work through the session, mode, and storage checks.
Why did only my rate change fail, while other settings saved?
That pattern points to wrong mode or profile for the rate section, or to a partial save fault. Check that you edited the rate table for the mode customers actually use, and test as a customer in that mode, before concluding storage is at fault.
How do I know a save actually worked?
Reload the admin page, check the setting again, and if the platform prompts for a reboot, reboot and check again. Then test as a customer with a small payment in the correct mode. A change that survives reload, reboot, and a customer test has saved correctly.
