mesmerize – page content – latest news

Good evening.
I really need your help.
I set up the homepage with mesmerize by inserting various contents.
One of them is “breaking news” which shows the latest articles created.
Now, under the last three news, there is a default button that refers to a category that shows all the articles, called “blog”.
The problem is that I have no access and management of the blog page (I can’t find it in articles, categories, tags, pages). Also because it shows articles that should not be seen except by accessing from specially prepared links.

I have identified three possible solutions:
1. find this notorious blog page and try to edit it. But no one knows where it is.
2. modify the link of this button and redirect it to the category I want. The problem is that the theme does not give me this possibility. I should work on php but I can’t find the script to edit it.
3. delete this button and insert another button as an element. In this case, it gives me the possibility to decide the link. Again I can’t find the script to delete the button.

PS. when I inspect the site and look for the button it appears to me as
GO TO ARCHIVE
Here I would like to change that link: “http://accmar-santostefano.it/?post_type=post”

I hope you can help me because this content is really important for my site.
Thanks in advance for the support.
Daniele
