## 설명

The **Plugin Compatibility Checker** helps you keep your WordPress site stable and
secure by scanning installed plugins for PHP, Database, and WordPress version compatibility.

**🆕 WordPress 7.0 Database Readiness**
 WordPress 7.0 introduces stricter database
requirements (MySQL 8.0+ / MariaDB 10.6+). Many hosting environments still run older
database versions which may silently block updates. This plugin now detects database
compatibility and warns you before upgrading.

**$1/month License Required (Entry Plan)**
 You must subscribe to the CompatShield
Portal ($1/month recurring) to obtain a **license key**. Once activated, you will
be able to see plugin compatibility results (up to PHP 8.5) and database compatibility
directly inside your WordPress admin.

**📺 Video Tutorial**
 Watch step-by-step how to activate your license & run your
first scan:

**Quick Setup Steps**
 1) Subscribe  Get your license key from the Portal 2) Add
your domain inside the License tab 3) Copy your License Key 4) Paste License Key
inside Plugin Settings in WP Admin 5) Click **Validate License** 6) Click **Save
Settings** 7) Go to Plugin Main Page  Click **Rescan**

**Pro Version (Upgrade)**

Dashboard with advanced features — vulnerability summary, detailed scan results,
notifications, historic analysis, plugin issues overview, premium ZIP upload scanning,

## 설치

 1. Upload `plugin-compatibility-checker` to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the **Plugins** menu in WordPress.

    up to PHP 8.5 and database checks.

## FAQ

### What happens if I don’t activate a license?

You must subscribe to the $1/month entry plan and activate your license to see compatibility
results. Without license activation, visibility will be limited. Pro unlocks dashboard
analytics, notifications and vulnerability insights.

### Why is database compatibility important?

Starting with WordPress 7.0, database requirements are stricter (MySQL 8.0+ / MariaDB
10.6+). If your hosting is outdated, your site may not receive updates.

### Will my site break if database is outdated?

Not immediately, but your site may stop receiving future WordPress updates, which
can lead to security risks.

### Why does a plugin show “No Data”?

This usually means the plugin is either custom/premium or its version has been removed
from WordPress.org.

### Do I need to rescan after adding new plugins?

Yes, please click **Rescan** to include new plugins in the compatibility check.

My Wordpress was using a very old version of PHP and I kept getting warnings that
I soon would not be able to upgrade Wordpress any longer because my version of PHP
would no longer be supported. I wanted to make sure that all my plugins would be
compatible with PHP 8.3 because I didn’t want the PHP upgrade to somehow break my
site. I paid the reasonable $1 that the Compatibility Checker asked for a monthly
subscription, and it noted which of my plugins were not supported. I removed them
and had a successful upgrade to PHP 8.3 without breaking my site. The support folks
for this plugin respond instantly in their webchat when I had questions.

 [Pieter Sand](https://profiles.wordpress.org/beachholiday/) 2026년 6월 10일

This is a fantastic plugin that saves a lot of time and prevents problems during
version upgrades to PHP and also Wordpress itself. We can highly recommend it and
it is worth the optional paid subscription.

The free version gave me a basic idea, but the paid version was way more useful.
It caught PHP issues that I wouldn’t have noticed before updating. Glad I upgraded
because it saved me time fixing errors later. Definitely more helpful when running
sites on newer PHP versions.

 [bhammondCVL](https://profiles.wordpress.org/bhammondcvl/) 2025년 11월 3일

The plugin will only check major-version compatibility (6, 7, 8) without paying 
$20/month for a service subscription. If you want to try that, go for it. The free
version, though, will not tell you much that is useful.

The plugin checks in free version up to php 8.0+ compatibility. Who needs to know
if a plugin is compatible with an obsolete version of php ?
