# Enable system properties for Knowledge Center

To use the Knowledge Center plugin, you must enable the system properties before you configure the space.

## Before you begin

The default system properties settings for Knowledge Center:

-   **For new users:** All properties are enabled \(set to **true**\) by default.
-   **For existing users:** All properties are turned off \(set to **false**\) by default to avoid disrupting current workflows or customizations. Existing users must enable the properties to access KC and its features.

**Supporting releases**: Knowledge Center and its features are available to the users in Yokohama Patch 11 \(YP11\) and Zurich Patch \(ZP4\) releases.

Role required: admin

## Procedure

1.  Navigate to **All** > **System Properties**.

    \[Omitted image "KC-AO-system-properties.jpeg"\] Alt text: Knowledge Centre system properties.

2.  Enable the following system properties by setting the parameter to **true**.

**__sn\_km\_center.glide.knowman.enable__**

</td><td>

Provides access to the Knowledge Center and its features. It must be set to true to enable agents to access the plugin and use its features.

</td></tr><tr><td id="d581787e156">

**__sn\_km\_center.glide.knowman.ece.enable__**

</td><td>

Governs access to the Knowledge Center Article Editor. If set to true, you get access to the enhanced editor capabilities. If set to false, the legacy TinyMCE editor remains available. As there are compatibility gaps between Article Editor and TinyMCE, you can choose based on your training and workflow requirements. Disabling this property also restricts access to article optimization features.

</td></tr><tr><td id="d581787e170">

**__sn\_km\_center.glide.knowman.redirect.enable__**

</td><td>

Controls how links to the Knowledge Center behave. If set to true, all KC features are available in the updated interface. If set to false, users are redirected to the Core UI interface, which may be necessary for customizations incompatible with the updated interface. You can use KC features while retaining access to legacy forms for compatibility.

</td></tr><tr><td id="d581787e189">

**__sn\_km\_center.ao\_auto\_update.enabled__**

</td><td>
