Prestashop 1.6 view customer page from back office not charging styles nor templates

[David]

I'm using Prestashop 1.6.1.17.

When I go to Customers menu in the back office and I click on "View" for any customer from the list, the page is loaded with unformatted text. Besides, I cannot see any other templates like the header or the footer. After inspecting elements there are no errors in the console, and I don't see anything in the head tag.

However, I see an error in the information at the end of the page (see the picture):

On the other hand, if I click on "Edit" for any customer from the list the page loads correctly, and all the other pages from the back office work well as well.
