Hello,

My channel manager preview is blank sometimes. It just shoes the white page.

I checked the Channel Manager troubleshooting page which says I need to set X-Frame-Options response header value to SAMEORIGIN.

> **[Channel Manager Troubleshooting - Enterprise Java Content management system -...](https://www.onehippo.org/library/concepts/channels/channel-manager-troubleshooting.html#opening_channel_blank_page)**
>
> Hippo Open Source Enterprise Content Management

Any idea how to get this done?

Thanks,  
Rakesh

I am not aware of issues wrt channel mgr in 12.2.0. Perhaps you can check whether there are javascript errors when it happens, or whether there are server logs indicating a problem

Regards Ard

That’s a spring issue. See:  
[https://docs.spring.io/spring-security/site/docs/5.1.3.RELEASE/reference/htmlsingle/#headers](https://docs.spring.io/spring-security/site/docs/5.1.3.RELEASE/reference/htmlsingle/#headers)
