I've edited a Power Page site header using one template without any problems, but trying to do the same with the Community Dynamics template results in an error, that I can't resolve.
Your updates may not show on the site because of customizations to the code made by someone in your org.Learn more
The solution is given as:
To resolve this issue, open the Mobile Header content snippet in the Portal Management app and update the source code with the correct attribute values for each snippet as in the example below.
I get the same error if I start again with the base template.
I can open Portal Management, locate Content Snippets under Content and scroll to the Mobile Header entry.
I think I need to update the value, possibly using the MS provided example?
That gets rid of the error message, but the site header still doesn't change?
Well I can change the Layout i.e. reduce screen size, but not the site Title + logo.
