What is CMSimple?

CMSimple is a content management system (CMS), which requires no database. All data are stored in 2 files, content.htm (content) and pagedata.php (page-related data).

The installation is very easy:

  • Unzip the download
  • Upload folders and files to the web server
  • For some files, assign the necessary write permissions
  • Done. Now you can log in and work with CMSimple.
