Drupal 7

Using a CKEditor could be a significant help for managers when working with the website content.

Drupal 8 is the most popular Drupal version. A great number of documentation and articles is available to facilitate the Drupal configuration.

Drupal is a free open source solution, which predetermined its development. Like other similar CMS, it has a developed user community, which creates modules, patches, and thematic assemblies based on the core. Exist thousands of articles describing how secure and flexible Drupal is.  The core of the system itself provides few content management tools. This is not the mistake of the creators, but a conscious decision that emphasizes the flexibility of the system and its focus on experienced developers - or those, who are willing to learn, read forums and watch video manuals. But even in this minimal set of tools, some parts are very useful for the future site - for example, pre-installed tools for organizing user accounts. They help develop large portals with forums and other social ways visitors interact.
