v1.2 — 22-06-2026
Speed tiers via Configurable Options, an automated welcome email with connection configs, a clearer One-Time Link, and a cleaner client-area overview.
Configurable Options — speed presets

One-click creator — a Create speed presets button on the product Module Settings tab builds the WHMCS Configurable Options for Download limit (Mbit/s) and Upload limit (Mbit/s), adds the presets (Unlimited, 10, 25, 50, 100, 250, 500, 1000 Mbit/s) priced at 0 in every currency, and links the group to the product. Idempotent — safe to click repeatedly.

Per-order speed — the customer's selected value overrides the product's default download/upload limit. Applied on provisioning and on every upgrade/downgrade (WHMCS calls change-package for configurable-option changes as well).
Per-tier pricing can be set on the sub-options to charge for faster speeds.

Welcome email

Optional welcome email sent on provisioning, containing the connection details, full WireGuard config text and an inline QR code, plus a manage-service link.
Selectable template — use any WHMCS Product/Service template or the bundled PUQ VPNcp - Welcome, with Create if missing / Reset to default buttons. The template is auto-created on first send if absent.

Resend welcome email button on the admin service tab; works regardless of the per-product auto-send setting.

One-Time Link

The client-area One-Time Link now includes a description, an Open link button, and a notice stating it carries every protocol config, QR code and credential and can be opened only once.

Client area

The default WHMCS Domain / Username / Server Name / IP Address / Visit Website block is hidden on the service overview, as it is not relevant for VPN products.

Maintenance

Admin AJAX endpoints made POST-only; output-escaping fixes; minor edge-case corrections.

v1.1 18-06-2026
Bug fixes

Client area blank page — fixed output-buffer conflict in the AJAX controller: WHMCS buffered HTML was prepended to JSON responses, causing the client area to render nothing

VPN session list false-positive error — the /client/online endpoint returning an empty list [] (no active sessions) was incorrectly treated as an API failure; now handled correctly

Smarty template security error — replaced blocked {$smarty.get.id} superglobal access (disallowed by WHMCS Smarty security policy) with the safe {$service->service_id} in client area and traffic statistics templates

Wrong default API port — HTTP connections to the PUQVPNCP panel were falling back to port 80 instead of the correct default 8098; fixed in all four code locations across three files

AJAX responses on inactive services — AJAX requests for suspended or terminated services now return a proper JSON error response instead of an empty string, preventing JavaScript parse errors in the client area
