PhalconCMS

Requires PHP 5.6+ and Phalcon 3.0+, which are older versions lacking modern PHP features, security updates, and long-term support, as noted in the README.

Installation involves multiple manual steps like database import, Nginx config editing, and permission changes, which can be error-prone and requires server administration skills.

Focused solely on basic blogging with no built-in support for plugins, advanced user roles, or content types beyond posts, restricting use for broader CMS needs.

Default admin credentials (admin/654321) are hard-coded and openly mentioned in the README, posing a significant security risk if not changed immediately after installation.
