Iportant problem with pages

Hello, I have one blog with wordpress: https://www.wotevar.es.

Since I created it, I have one important problem:

When I go to the 2nd, 3rd, 4th … page it don’t appeared.

You can try it: go to the foot of https://www.wotevar.es and click in page 2 for example, this is what appeared: https://www.wotevar.es/page/2

I try to put diferent plugins, I put difernt themes and i update wordpress.

Thanks
