Re: Changing Banner deppending by ...
I have found the solution.
I put it because in case some day someone who has the same question is with this post can have the solution.
I activated the option of themes by groups (I did not know it existed) and with that I have assigned the subject that I wanted to the group. In my example, I have only set up football so that when the users that belong to that group enter, load the soccer theme. The others, having no configured anything will load the default theme of the site.
Regarding the logo, I have duplicated the default theme, and with a CSS selector I change the logo that I want to put on.
The more you touch and try, the more things you discover.
Greetings and thanks anyway
