# Error reference

If RelyAI shows a message you don't recognise, find it below. Messages are grouped by area, with a
short note on what each one means and how to clear it. For step-by-step help see
[Troubleshooting](/relyai-acellemail/troubleshooting).

## ionCube

RelyAI ships as an ionCube-encoded build. If the **ionCube Loader** is missing or too old, the
plugin's encoded files can't run and RelyAI won't load at all. Install or enable **ionCube Loader
13.0.2 or newer** for your PHP version, then reload. See
[Requirements](/relyai-acellemail/requirements).

## License and access

| Message | Meaning and fix |
| --- | --- |
| "Enter a valid RelyAI license key to enable AI features." | No key is registered yet. Add and **Activate** your key under **RelyAI → Settings → License**. |
| "Your RelyAI license could not be verified. Please check your key." | The key failed verification. Confirm the key, then **Re-activate** on the License tab. |
| "RelyAI is not licensed on this install. Ask an administrator to activate a license key." | An AI request ran while unlicensed. An admin must activate a valid key for this domain. |
| "License could not be activated: :reason" | Activation was rejected; the reason is shown. Fix the stated cause (domain, IP, or install path) and try again. |
| "License deactivated on this domain." | Confirms the key was released from this domain. Re-activate here or on another domain to restore AI. |

## Engine and API key

| Message | Meaning and fix |
| --- | --- |
| "No AI API key is configured. Please set one in Admin → RelyAI → Settings." | No engine key is set. Add an engine and key under **RelyAI → Settings → Engines & Keys**. |
| "Connection successful" | The **Test Connection** check passed — your engine and key work. |

See [Connect an engine](/relyai-acellemail/guides/connect-an-engine).

## Updates

| Message | Meaning and fix |
| --- | --- |
| "Could not reach the update server (…). Your plugin continues to work normally." | The updater couldn't reach the server — often just because no release is published yet. AI keeps working; try again later. |
| "Your Support & Updates plan has expired or is not active…" | Installing new releases is blocked for this key. Renew Support & Updates; the installed version keeps working. |
| "v:v is published but its download is not yet available — please contact support." | A release exists but its download isn't ready. Contact support. |
| "Update failed: :reason" | The update didn't apply; the current version is auto-restored. Check the reason and retry, or update manually. |
| Verification failed during an update | The downloaded build failed its integrity check and was not applied. Retry, or update manually via **Admin → Plugins → Upload Plugin**. |
