I find a solution, please share with other if they have same problem.

1.- Install Advance Text Widget Plugin
2. To call “tubepress” short code don´t use this: [tubepress], you have to use

<?php echo apply_filters('the_content', '[tubepress]'); ?>

This is the only way I could make this works, if someone has same problem, this is the solution.

TagDiv, I don´t know why this happens but I recommend that we could use php on default text widget to avoid installing other plugins.

Thanks a lot. Yes, just this shortcode, but I don´t understand why. Those shortecodes that came from Newspapaer theme works, but this one that doesn´t.

I mean [tubepress]

Thanks a lot. I found the way. I leave it here to help people who´s going to do same thing:

Just find class:

td-grid-wrap

And modify his padding and margin attributes from the header type you´re using on your configuration.

Thanks. This is my site:

If this could be done. Please, write a step by step about it.

I have tested to try to fix and just was that the Visual editor of wordpress was deactivated. This means that “Text Block” from Visual composer depends on this to work. ¡Do not deactivate “wordpress visual editor” you will have problems with some blocks.
