Requirements
This page lists everything your site needs to run Unblock.
Minimum requirements
| Requirement | Minimum | Recommended |
|---|---|---|
| WordPress | 6.7+ | Latest |

WordPress
Unblock requires WordPress 6.7 or higher. It uses Block Editor APIs that aren't available in older versions.
Unblock works exclusively with the Block Editor (Gutenberg). It does not support the Classic Editor plugin or page builders like Elementor or Divi.
Themes
Any theme that supports the Block Editor works — block themes (Full Site Editing) and classic themes with block support.
Unblock comes with a blank companion theme — Unblock Theme — with zero CSS opinions. It's the recommended starting point for new sites. See Install the Unblock Theme for details.
The Classic Editor plugin disables the Block Editor entirely. If you have it active, Unblock won't load. Deactivate Classic Editor before installing Unblock.
PHP
Unblock uses modern PHP features (strict types, enums, readonly properties) and requires PHP 8.1+. PHP 8.2 or higher is recommended.
The intl extension is optional but recommended for internationalization filters (date, number, and currency formatting).
Checking your environment
Go to Tools → Site Health in WordPress admin. The Info tab shows your PHP version, memory limit, and other server details.
