# Error reference

Search this page for the exact wording you saw. Each entry quotes the message verbatim, explains
what it means, and tells you what to do. For step-by-step fixes, see
[Troubleshooting](/gst-manager-whmcs/troubleshooting).

## ionCube Loader

> `ionCube Loader required. Contact support@relyweb.co`

**What it means:** The GST Manager release is ionCube-encoded, and your server is missing an
ionCube Loader or running one that's too old for your PHP version.

**What to do:** Ask your host to install/enable the **ionCube Loader** for your PHP version, then
reload the page. WHMCS's own minimum loaders already satisfy GST Manager (PHP 8.2 → 13.0.2,
PHP 8.3 → 14.4.0; Loader 15.x also works). See [Requirements](/gst-manager-whmcs/requirements).

## Activation

> "Activation failed. Check activity log for details."

**What it means:** Something went wrong while activating the addon under
**Setup → Addon Modules** — for example, the database tables, templates, hooks or tax rules
couldn't be set up.

**What to do:** Open the WHMCS **Activity Log** for the specific error, resolve it (commonly file
permissions or PHP requirements), and activate again. If it persists, contact
`support@relyweb.co` with the log entry.

## Update & license messages

These appear around **Global Settings → Update Status** and **License Information**. Your installed
version keeps working through all of them; they only affect updating.

> "Your Support & Updates plan has expired…"

**What it means:** Your **Lifetime** license's Support & Updates entitlement has lapsed.

**What to do:** Your current version keeps working forever — renew Support & Updates to install
newer versions. See [Licensing](/gst-manager-whmcs/licensing).

***

> "Could not verify your license right now…"

**What it means:** The licensing server was briefly unreachable. This is transient.

**What to do:** Wait a moment and retry **Update Now**. No action is needed if you weren't trying
to update.

***

> "… is published but its download is not yet available"

**What it means:** A new release has been announced, but its installer isn't live yet.

**What to do:** Nothing — **Update Now** stays disabled until the download is ready. Try again
later.

***

> "Failed to download update…"

**What it means:** The update package couldn't be downloaded — usually outbound HTTPS is blocked,
or the build isn't authorised for your license.

**What to do:** Allow outbound HTTPS from your server, confirm your license is **Active**, and
retry. If it continues, contact `support@relyweb.co`.

***

> "Backup verification failed…"

**What it means:** The pre-update backup couldn't be verified, so the update **stopped before
changing anything**.

**What to do:** Check that the install directory is **writable** and that you have enough **disk
space**, then retry **Update Now**.

## Setup wizard

On **step 3 (GSTIN & Tax Rules)**, an invalid **GSTIN** (your 15-character GST registration
number) is shown in **red** at the top of the step. This step is blocking — enter a valid
15-character GSTIN and pick your registered state to continue. See
[Troubleshooting](/gst-manager-whmcs/troubleshooting#the-setup-wizard-keeps-appearing).
