Free multimodule for WHMCS

Before using the module, generate unique salts and put them in module_init.php. The module was has full Apache support (100%). It may also work with Nginx, but language routing on the home page can require extra configuration and testing.

ZMChel WHMCS Multimodule is free. It lets you manage site content from the WHMCS admin area. Its tools include a visual page and block editor, multilingual content, menus, a media library, SEO metadata, XML sitemaps, redirects, rewrite rules, and import/export.

Future development:

Add nested pages and page categories or sections.
Split the current monolith into interacting components.
Add an admin access rights manager for the module.
Expand the default language list in supported_langs.php.
Add an admin code editor to create, edit, and delete module .tpl files and edit CMS client theme files (excluding the admin theme).
Add a language manager for editing language files of this module, other modules, and the CMS itself.
Improve the media manager.
Build a full, more optimized SEO manager inspired by Yoast SEO for WordPress.
Add multilingual sitemap generation and an HTML sitemap page.
Add usage statistics to the page manager.
Add an optimization manager for JS, CSS, and HTML minification, full-page caching generated by the module, and optimization of module and WHMCS database tables.
Add a proper module update system.

These are ideas for the future, not a fixed roadmap.
