WP archive.php does not work

Question

I have problem with my page http://velvetart.net

When I want to see monthly archive (http://velvetart.net/2013/10/) design is totally upside-down :/ I thought, when archive.php file is missing, WP use for archive page index.php instead, but then, why is my archive messy? :(

I try to upload archive.php, date.php, category.php, taxonomy.php, author.php, tag.php (all these files were same as index.php), but still look the same way :/ Please, does anyone know what to do with that? Thank you very much

Answer 1

The problem occur because of date class used in body tag as well as inside body container( used in the post date).

Solution:

In style.css, go to line no 321 and change .date to #maincontainer .date
