.htaccess and wordpress

Hello
I have a problem with the format of wordpress pages. Firstly, I did not know what was causing the problem.
www.arreglaordenador.com/blog

The .htaccess file from the root, that is to say,www.arreglaordenador.com is the one causing the problem because when I removed that file the format of the blog's pages was correct. The thing is that i need that .htaccess file for te rest of the site www.arreglaordenador.com. So,
how do you suggest modifying the .htaccess file to let the blog pages display properly when you browse
www.arreglaordenador.com/blog?
Thanks a lot

 

can you copy paste what text you had on .htaccess

 

Already solved by adding a new .htaccess access folder in the wordpress installation folder with this code:

DirectoryIndex index.php

Code (markup):

Thanks though.
