Without making any change - or at least that I can remember - the index.php is not loading properly.
you can see it here: http://reginademiguel.net/noticias/
Rest of the site is working fine and the header is loading properly. It is the posts index.php that isn't working.
As you can see here single post page work fine too:
I tried changing the file, uploading other themes index.php, or simply writing some text into it to see if it loads. Nothing will affect it.
¿Any clues on how to solve this?
Thanks in advance.
