Hi Antonio,
By 'don't have the full components' do you mean modules that you assigned are not showing on the page?
If that is so, after investigating your site, it seems there are a few issues causing this.
First issue:
There are two similar menu items for your blog page. One under 'Aseguratemexico' and another under 'Navigation'. Both of these menu items contain the same alias, 'blog'. But, only one of them is the real menu item for your blog page, which is the one under 'Navigation'. To avoid future confusion, I suggest you to rename the alias of the blog menu item under 'Aseguratemexico' to something else.
Second issue:
It seems your cache system is not registering the changes I made to the site. For example, I tried changing templates or assigning modules to menu items but those changes are not applied to the site. After turning off your cache in Global Configuration and disabling two cache plugins in your Plugins page, I was able to see the changes applied immediately. Therefore, I recommend that you look into these cache configuration and see if you can improve it or just disable it if you wish to.
For now I have revert your cache configurations back to your original setting.
Third issue:
Regarding your template, it seems your Responsivizer template is assigned to the wrong blog menu item as mentioned above. I`m not sure which template you would like to use in your blog page. For now I have temporarily assigned AM_34 template to your blog page and configure a module to show on the left side.
I hoped these explanations helped you understand your issues regarding assigning modules. If you are not referring to modules, perhaps you can let me know what you meant by 'full components'.
