Hi, I probably haven't explained my problem well. I created 4 categories and they were first displayed in 4 different pages (one per category). Lately, however, all the items are displayed together on the same page. I need to keep the distinction of categories per page.

Keep a backup and recreate this portion

Is there no way to fix it? Should I re-create 4 pages full of data? But isn't there another solution? Before, everything worked fine

Hi it's a question for component developer. In my sites I use only one category and it works fine.

but the component is not yours?
