Requirements
Before you install GST Manager, take a minute to confirm your server meets a short list of requirements. Everything here is standard for a modern AcelleMail install, so if you are already running AcelleMail 4.2 you are almost certainly ready — but it is worth checking so activation goes smoothly the first time.
Server and software
| Requirement | Details |
|---|---|
| AcelleMail | 4.2.0 or newer |
| PHP | 8.2 or newer (runs on 8.2, 8.3, 8.4 and 8.5) |
| ionCube Loader | 13.0.2 or newer (see below) |
| SSH access | Needed once, to apply the plugin's core hook points |
| License | An active GST Manager license |
The ionCube Loader
GST Manager ships as an ionCube-encoded build, so your server needs the ionCube Loader — a small, standard PHP extension that runs protected commercial software. It is the same Loader AcelleMail itself requires, so a server already running AcelleMail almost always has it and you rarely need to install anything new.
You need ionCube Loader 13.0.2 or newer. One encoded archive covers every supported PHP version from 8.2 to 8.5, and newer 14.x and 15.x Loaders are backward-compatible — so there is nothing to match up.
GST Manager will not run without ionCube
If the Loader is missing or too old, activation fails with:
ionCube Loader required. Contact [email protected]
Install (or update) the ionCube Loader for your PHP version, then activate the plugin again.
Why a GST Manager license
The license gates the whole GST admin surface. Until a valid key is Active, the plugin shows only its License page — the dashboard, Setup and Reports stay locked. Enter your key first and everything opens up. See Licensing for how the check works and where to manage your key.
Why SSH access
GST Manager needs to hook into a few points in AcelleMail's invoicing flow. You do this once, from a shell on the server, by running a small install script that adds those hook points. It is idempotent — safe to run again after upgrades — and once done you never need SSH again for day-to-day use. The Installation guide walks you through the exact command.
How to check
- AcelleMail version — your admin footer shows the running version; confirm it is 4.2.0 or newer.
- PHP version — run
php -von the server, or check your hosting panel. - ionCube Loader —
php -mshould listionCube Loader; if it does not, install it for your PHP version. - SSH — confirm you can log in to the AcelleMail Laravel root over SSH.
