php -v shows one PHP, but most servers run several at once: CLI, a PHP-FPM service per version, Docker containers and control panel builds. Here is how I found all of them on my own VPS before the 21 October 2026 PHP security release.
bin/magento --version says 2.4.9 whether your store has every 2026 isolated patch or none. This checklist shows how to check missing Magento security patches with vendor/bin/patch-status, per-patch dry runs that understand stacking, a CI gate, and a monthly routine.
The Magento 2 "Area code not set" and "Area code is already set" errors both come from one rule about when an area must exist. This guide fixes them fix-first for Magento 2.4.4 to 2.4.9 in custom console commands, bootstrap scripts, setup patches, and indexers, with full runnable code.
Forgot the Magento 2 admin password or stuck at the two-factor prompt after a new phone? This guide fixes both from the command line for Magento 2.4.4 to 2.4.9: the supported password reset, a safe database route, account unlock, and the real 2FA gotcha (server clock drift).
After a 2.4.7-p3 to 2.4.8-p3 upgrade, setup:upgrade throws 'Cannot instantiate interface AttributeRepositoryInterface'. The root cause is stale compiled DI. Here is the exact recovery recipe plus the extension audit to run if it returns.
setup:static-content:deploy compiles your theme into pub/static: CSS, JS, images, fonts and translations, per theme and locale. Here is what it builds, where it writes, and why production pages render unstyled without it.
setup:di:compile pre-generates the factories, proxies and interceptors Magento would otherwise build at runtime. Here is exactly what it generates, the nine operations it runs, and why production cannot skip it.
On the surface setup:upgrade just “applies updates.” Underneath it is an ordered pipeline that reconciles your database with your code. Here is exactly what runs, in what order, and which tables it writes.
When Magento cron stops firing, your store silently breaks: indexes go stale, transactional emails queue forever, and scheduled prices never apply. This guide covers the exact crontab lines, cron groups, cron_schedule diagnostics, and every root cause fix for Magento 2.4.4-2.4.9.
There are two honest ways to check whether a Magento extension is Hyvä-compatible, manual grep across the module source, and the hyva-themes/magento2-compatibility-checker CLI. Neither one catches everything. This post lists the exact bash one-liners I run against vendor/, walks through what the official Hyvä compat CLI flags and what it silently ignores (Magewire deps, GraphQL schema needs, form validation libs), and ends with the checklist I work through when the CLI prints "compatible" but the module still throws KO errors in the Hyvä storefront on Magento 2.4.4-2.4.9.
