Hi @conroyke56 Maybe you can have a look [at](https://www.bikalims.org/manual/introduction-and-overview/client-facing-lab-portal/replace-you-lims-favicon) and not sure if you got to this point > Click [Customize] and change the two instance of the text $portal_url/+plone+senaite.core.static/images/favicon.ico...

Maybe try on a new site or instance, even new container. It works for me

Our (senaite.impress.interfaces.ISenaiteImpressLayer)  and our (senaite.core.interfaces.ISenaiteCore) ``` ```

Yes, I have created a new site and this also saves ``` ```
