This plugin hasn’t been updated in over 2 years. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



SMF2WP is a simple one way bridge from Simple Machine Forum (v2.0.1 tested) to WordPress (v3.2.1 tested). This means, this one uses databases of SMF Forum and sync to WP database every time a user performs log-in action in both WP and SMF. To get this working, it is highly recommended that you have a fresh install of WordPress with an install of SMF. Also, WP and SMF must be installed in same domain, and should not be being accessed through a subdomain, though it still work. For example, if your website contains of WordPress for news and SMF for forum, if your news is, then your forums should be somewhere like

This plugin will do these following tasks:

  • If a user log in WP, then that user will be logged in SMF using SMF2API.
  • If a user logout WP, then that user will be logged out SMF using SMF2API.
  • If a user log in SMF, will be logged in WP as well.
  • If a user log out SMF, will be loged out WP as well.

*** I spent a lot of time for this plugin, please consider donating or at least giving me some encourage comments at my Website SMF2WP ***

Every time a user logged in SMF forum, same username (will be created if not exist) will be logged in WordPress. Because SMF is placed in higher order, so user in WordPress will be changed to SMF with same role.

For example, you have an administrator named “admin” in wordpress, after SMF2WP fully activated, the SMF user named “admin” can login as that administrator. So be careful!
