To run wpDiscuz 7 we recommend your host supports:

• PHP version 5.6 or greater
  • PHP Limits (recommended)
    • memory_limit = 128M or greater
    • upload_max_filesize = 128M or greater
    • post_max_size = 128M or greater
    • max_execution_time = 180
    • max_input_vars = 5000 or greater
  • PHP Multibit String Functions
    • mbstring.language = all
    • mbstring.internal_encoding = UTF-8
    • mbstring.http_input = auto
    • mbstring.http_output = UTF-8
    • mbstring.encoding_translation = On
    • mbstring.detect_order = UTF-8
    • mbstring.substitute_character = none;
    • mbstring.func_overload = 0
    • mbstring.strict_encoding = Off
• MySQL version 5.6 or greater
  • InnoDB support (recommended)
• Apache
  • mod_rewrite module (for clean URIs known as Permalinks)

That’s really it. We recommend Apache or Nginx as the most robust and featureful server for running wpDiscuz, but any server that supports PHP and MySQL will do. That said, we can’t test every possible environment and each of the hosts on our hosting page supports the above and more with no problems.
