# Solr - Error When Initializing Coveo When Side-by-Side With Solr Is Enabled
## Symptoms

* The Sitecore site goes down when enabling Solr.
* The generated stack trace shows that the error occurs when Coveo is trying to validate the Coveo Index configuration:

```text
[...]
Sitecore.Sites.SiteContextFactory.GetSiteContext(String name) +38
Coveo.Framework.Sites.SiteContextFactoryWrapper.GetSiteContext(String p_SiteName) +127
Coveo.Framework.Configuration.CoveoIndexConfiguration.Validate() +165
Coveo.SearchProvider.ProviderIndexBase.Initialize(IIndexDocumentPropertyMapper`1 p_DocumentTypeMapper) +2241
```

## Cause

Due to how Solr dependencies are injected into Sitecore, Coveo tries to validate its configuration before the site context is initialized.

## Resolution

Set the `skipSiteNameValidation` flag to `true` in the `Coveo.SearchProvider.Custom.config` configuration file.

```xml
<sitecore>
  <coveo>
    <defaultIndexConfiguration>
      <skipSiteNameValidation>true</skipSiteNameValidation>
    </defaultIndexConfiguration>
  </coveo>
</sitecore>
```
