# Issue opening the Diagnostic Page

[.version.no-link.c4sc.c4sc-instance.10]
Sitecore 10



[.version.c4sc.c4sc-issue-resolved.5-0-1202-1.February-15&-2023]
[Issue resolved](https://docs.coveo.com/en/m9ta0384#release-notes)


## Symptoms

You have installed Sitecore SXA and have an issue opening the **Coveo Diagnostic Page**.

## Cause

There's an issue with the way the `coveo_website` site is resolved in SXA.

## Resolution

This issue was fixed in the [February 15, 2023 release](https://docs.coveo.com/en/m9ta0384/).

### Workaround

. Open `<SITECORE_INSTANCE_ROOT>\App_Config\Modules\Coveo\Coveo.Authentication.config` in a text editor.

. Locate the `<federatedAuthentication>` element.

. Just above the `<federatedAuthentication>` element, add the following block.

```xml
<!-- SXA handles site resolving differently. With this added setting, the coveo_website will be properly resolved when needed. -->
<experienceAccelerator>
  <siteResolving>
    <site name="coveo_website" resolve="before" />
  </siteResolving>
</experienceAccelerator>
```

The beginning of the file should now be as follows:

```xml
<!--
    Do not modify this configuration file.
    Instead, you should patch this file using a Coveo.Authentication.Custom.config file.
-->
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/" xmlns:set="http://www.sitecore.net/xmlconfig/set/">
  <sitecore role:require="Standalone or ContentDelivery or ContentManagement">
    <!-- SXA handles site resolving differently. With this added setting, the coveo_website will be properly resolved when needed. -->
    <experienceAccelerator>
      <siteResolving>
        <site name="coveo_website" resolve="before" />
      </siteResolving>
    </experienceAccelerator>
    <federatedAuthentication type="Sitecore.Owin.Authentication.Configuration.FederatedAuthenticationConfiguration, Sitecore.Owin.Authentication">
```

. Save your changes.
