WordPress and Vanilla Forums Single Sign-on

Getting The WordPress Plugin

To make WordPress SSO work with Vanilla, you will need the free Vanilla Forums plugin. You can download it here. To install the plugin use the following steps:

  • Upload the vanilla-forums folder to /wp-content/plugins/
  • Activate the plugin through the ‘Plugins’ menu in WordPress

Note: You can also search for the plugin from the backend of your WordPress via the “add new” option in the plugin menu. Look for “Vanilla Forums” plugin created by Todd Burry.

Once you have installed the Vanilla Forums plugin, you will see the following added to your WordPress admin menu


Connecting WordPress To Your Vanilla Forum
To prepare Vanilla Forums for Single Sign-on with your WordPress website, enter the location of your forum. Simply fill in the URL for your forum and click save:


Note: The domain can be at myforum.vanilaforums.com or it can be the custom domain that you create (i.e. community.mysite.com).

If you run into validation issues or get the following error: “Couldn’t find a Vanilla Forum at this url :/”, the issue is related to where you host your WordPress install. The following checklist should help with the most common issues that cause this error and how to address them:

  • Forum is actually not at the url you used. Please recheck the URL.
  • DNS isn’t updated. If you created a custom domain, give the server some time to propagate.
  • Does PHP have cURL enabled? (just *having* cURL isn’t enough, it needs to be in the copy of php actually running web requests). If you are not sure if you have CURL, contact the host of your WordPress site to enable this.
  • There may be an issue to recognize the forum URL if the admin has been locked down with an .htaccess file. Check the file to make sure it is not.

Configuring Single Sign-On (SSO)

To setup SSO, click on the Single Sign-On menu item to get to the following screen. You will need to copy the values in these fields into the SSO settings on the your Vanilla jsConnect configuration page.

SSO WordPress Vanilla

Here are the elements explained and the next steps to follow:

  • Enable: If you check this, users to your Vanilla Forum will sign in through your WordPress login page.
  • Client ID: This is can be any numeric value or text value you set. Make sure it has no spaces or non-alphanumeric characters. You can use dashes (-) to separate words.
  • Secret:  Click “Generate” to create a secret key.
  • Other Information for Vanilla: These are values generated by your WordPress automatically, that you will need to copy to your Vanilla install. This information lets Vanilla know how to process your members.

The following is an example of how the Client ID you created and a Secret key generated in WordPress will look before you proceed:

Add Connection Vanilla

Keep your WordPress open and in another tab or window, login into your Vanilla Forum dashboard.

jsConnect in Vanilla Forums

Login into your Vanilla Forums backend, and click the  dashboard menu item “jsConnect” found in the User menu group. (Please note SSO is only available on the Advanced plan and greater. You will need to enable the jsConnect Plugin before you continue.)


The first step on the jsConnect screen is to enter the ClientID and Secret into the appropriate fields that you created in your WordPress install. The next step is to copy the url values from the backend of your WordPress install. Just copy and paste the three urls: Authenticate Url, Sign In Url and Register Url into your Vanilla Forum jsConnect configuration form. You can leave the signout url blank. Once complete it will look like the following:

You are almost done. Here are some options to consider in Vanilla Forums backend:

  • “This is trusted connection and can sync roles & permissions”: This ensures roles and permissions sync between the two systems. To make this works properly you need to ensure the WordPress and Vanilla username groups are the same. So for example in WordPress you may have Author or Subscriber roles. You should create these user groups in your Vanilla install as well. You can do this by click on “Roles & Permissions” in the Vanilla Forums backend and “add role”. Note: Any user created in the forum prior to jsconnect will not be synced.

  • “Make this connection your default signin method”: This will force people signing into your Vanilla Forum to go through your WordPress login screen. You need to check this for the SSO to work as intended through your WordPress login page.

  • Advanced section: You can control the hash method and test the connection to ensure it’s working.

Change Registration Type

The final step, is to change the way users register with the site. To do this, go to the User menu in the dashboard and select “registration”.  When using SSO, you will want to change the method to the connect option.
