Hi Giulia,
First of all in the homepage I visualize the showcase module with featured articles as I did for the precedent version where there were 2 links: subscription to blog and RSS
I want it appears as the precedent version , how can do it?
Unfortunately, there is no setting to revert back to that look.
Also if i click on an article blog, I expect to see the link on the toolbar as you showed in your image, but it is different on my side (see the attache file) and also there is any RSS link, how can I do it in the same way you show me?
For the RSS link, make sure your backend setting
Settings>General>RSS Feeds>Enable RSS Feeds is enabled, also make sure the ACL of the user group permits them to subscribe via RSS.
For the toolbar layout, can you try disable this option and see if it works?

If not, try switching to our default protostar template and see if it works. Hope this helps.
