Topic on Skin talk:Citizen

The problem has been resolved.

When added a comment from the Extension: Extension:PageDisqus Position Very Wide, Is there a solution?

Do you have a screenshot or a demo of the issue? I don't have experience with the extension so I can't say I understand the issue.

This is example infitaah.id/wiki when added Extension:Pagedisqus.

Add this to the MediaWiki:Citizen.css page on your wiki, it should fix it.

#mw-data-after-content > h2,
#disqus_thread {
    max-width: var( --width-layout );
    margin: 0 auto;
    padding: 0 20px;
}

Thank you for the help... :)
