Site on CMS own development

The site was made by me on my own CMS, designed to create corporate websites, including with a product catalog (without the store functions).Although its capabilities significantly exceed the needs of this site, this CMS has been used for its beta testing.The structure of the MVC, modular, core functions can be modified using plugins.The administrator is available to edit the content and code of templates and modules (HTML, CSS, PHP), but separately on different administrator pages, which excludes the possibility of damage to the site when administered by a non-professional.The content is not combined with a layer anywhere, it is inserted into arbitrarily created in any number of fields of different types.The database of the second normal form with the tables of Nested Sets.The Postal Form Designer.The server response time is less than 80ms (in average - 50ms).Strengthening measures to protect the adminka.Plus, the admin is absolutely autonomous.Its folder can be physically removed from the server, and then returned back - on the frontend work it is not reflected at all.
