Categories not working

[kittysgifts]

Hello,

The blog categories aren't working properly.

For instance, take my category "Passo-a-Passo":
https://www.kittysgifts.com/blog/category/2-passo-a-passo

The posts from this category are not visible, and when clicking the "ler mais" ("read more") button, the article link always appears as:

"https://www.kittysgifts.com/blog/post-"

(All articles share the same incorrect link.)

Here is an example of a valid link from this category:
https://www.kittysgifts.com/blog/post/2-lacre

System details:

Everpsblog version: 5.6.3
Prestashop version: 8.2.1
PHP version: 8.1.31

Please let me know if you need any further details.

Thanks in advance.

Best regards,
Sónia
