This plugin hasn’t been tested with the latest 3 major releases of WordPress. 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.

IMPORTANCE: After installation, please read OTHER NOTES for further instructions.

*** 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!

Demo Sites

Well, have a look at


You need to have a working installation of SMF, and it is preferred to have a new WP installation. You must have SMF installed as a directory within your domain. Your forum and WordPress installations should not be on different domains or subdomains! Your blog on and forum on will not work!

For example, if you access your blog from, your wordpress installation is at, then it is possible that you can access your forum at

  1. Upload smf2wp to the /wp-content/plugins/ directory
  2. Uncheck “Enable local storage of cookies” and “Use subdomain independent cookie” in SMF. You can turn it off from Admin>Configuration>Server Settings…>Cookies and Sessions
  3. Activate the plugin through the ‘Plugins’ menu in WordPress
  4. Visit SMF2WP Settings in your Admin Settings section, enter relative URI to your forum, then Save it. If it is accessible, then at this point, SMF2WP is fully activated.
