To run an SMF forum the server it resides on, as well as the browsers used by its users, will need to meet some specified requirements. Additionally, there are some recommended requirements that may give advanced capabilities to users. Basic Server Requirements---- Any webserver that has approximately six megabytes of available disk space, and properly supports PHP, such as Apache or Internet Information Services (IIS). The following is required to be installed on the server: PHP 4.1.0 or higher. The following are required to be set correctly in your php.ini file:

  • the engine directive must be On.
  • magic_quotes_sybase directive must be set to Off.
  • session.save_path directive must be set to a valid directory, or empty.
  • file_uploads directive must be On.
  • upload_tmp_dir must be set to a valid directory, or empty.

Database capabilities such as MySQL 3.23.28 or higher, PostgreSQL 7.4.10 or higher, or SQLite 1.x or 2.x.

  • A minimum of 500 kilobytes of storage space in the database, although more is highly recommended.
  • The database user should have the following privileges (at minimum): SELECT, INSERT, UPDATE, DELETE, ALTER, and INDEX.
  • The database user should have CREATE and DROP privileges during install, upgrade, and conversion processes.
