Create & rename categories

Hello Community,
Pleased to meet, I am totally new on this platform, have limited knowledge on web design, and require some help.
Because of its interesting layout and to create a multi-disciplined event page, I selected the template: “blog-explore-let’s do it together”.
This layout fits me just fine, but I seem to be unable to rename the different categories (such as nature, photography relaxation, …)
Could somebody advise,
Many thanks,

Hi Olivier,

It doesn’t look like your site’s read-only link came through. Can you copy/paste that here? I’d love to take a look and see if I can help out!
