empty field

Hello!
There was such problem: the right of the article ostaetsya empty box (highlighted in red). Modules are not there.
Until the last moment, on other sites, such problems do not arise, or I did not notice it.
empty box must be removed to do this? Whatever text was the entire width.

Hi
check that you have no module published in this position. If a module is published (even if it renders nothing), the area is created, else it it not

Thank you! It helped! The problem was in the module settings.
