Hi @juninho235532 

Greetings from Freshdesk community!

The theme which you are looking for, is the mint theme which was there in the previous version of portals. I’m attaching a zip file for this theme which you can modify and import under Admin>Channels>Portals>Customize.

Here is an article which you might find useful in customizing your portal.

Feel free to drop a note here incase of further assistance :)

Best,
Barun
