Hey there, I wanted to try the new page publication feature on my instance and got an error 500 when opening the link in a tab. Tried with both public & private topics. I just tried to rebuild to the latest available commit [629ee5494d](https://github.com/discourse/discourse/commits/629ee5494d572fbd35db648358088d5c7e5a426a) but the issue persists.

The error you are reporting comes from [https://github.com/discourse/discourse/blob/master/app/views/published\_pages/show.html.erb#L6](https://github.com/discourse/discourse/blob/master/app/views/published_pages/show.html.erb#L6). It’s trying to find the URL of the logo that’s been set by your site’s `logo_small` setting. I can reproduce that error by deleting the logo that’s set by my site’s `logo_small` setting. If you have not set a small logo for your site, setting one should get rid of the error. I think this is something that needs to be fixed in the Discourse code though. Not having set a small logo should not create a fatal error when going to a published page. ---

[https://github.com/discourse/discourse/commit/6b818fb855e7520f44e2fac2ebe7353d8f2f3357](https://github.com/discourse/discourse/commit/6b818fb855e7520f44e2fac2ebe7353d8f2f3357) I think we should use site title if both logos are not available. But in the current UI, it looks not good since we have page title next to it. Maybe we should move page title from the site header like in the below examples? ![Screenshot 2020-09-21 at 11.41.13 AM](https://global.discourse-cdn.com/meta/original/3X/c/d/cda707cc5bcb2faeea2de52dc44862872eee94be.png) ![Screenshot 2020-09-21 at 11.39.57 AM](https://global.discourse-cdn.com/meta/original/3X/2/b/2b09b748eb2f005c063bc106043293f5877912d5.png) ---
