I'm trying to explain the problem:

If we navigate to “Actividades”(https://desarrollo.alhaurinesdeporte.es/actividades/) and click on “Pabellón Deportivo Municipal El Limón. We navigate to a new page that changes the url: "https://desarrollo.alhaurinesdeporte.es/actividad/pabellon-el-limon/"

If I click on “Actividad” (https://desarrollo.alhaurinesdeporte.es/actividad/) within this page, I navigate to a blank page. I want you to get to the top “Actividades” where all the activities appear

All this also happens to me in another section of the web, in “Instalaciones":

If you navigate to “Instalaciones" (https://desarrollo.alhaurinesdeporte.es/instalaciones/) and click on "Mirador el Lagar" or any image You will be taken to a new page that changes the url: "https://desarrollo.alhaurinesdeporte.es/instalacion/mirador-el-lagar/"

If I click on "proyecto" in this page (https://desarrollo.alhaurinesdeporte.es/instalacion/), I get to a very messy page. I want to get to the beginning “Instalaciones” where all the installations appear

In this case I also want to change the name of “proyecto" to “instalaciones” en la parte de navegación.

Adjunto varias imagenes por si les sirve de ejemplo, tambien pueden comprobrar ustedes el funcionamiento

No problem. But I want to be able to change the website that is blank and has nothing and the website that has a very ugly design.
How can I make those changes.

Thank you very much.

Here are the photos

No, the problem remains, nothing has been solved.

In the previous message you have the images of how the web looks like.
I can't leave it like that, if I can't change the path, at least I can change those two pages.
